Interior - Seats and Belts

Short answer: Yes — shoulder belts were available in first-gen convertibles; the 1969 Fisher Body Manual shows front and rear installation. The front belt’s outer strap anchored near the convertible-top pivot (coming through the box around the top mounts); the rear belt’s outer strap mounted in the trunk at one of the cocktail-shaker bolts.

Look at the upright rear-seat support of any F-body convertible — there’s a ~3″ indentation on each side for the belt to pass over. (One oddity: a rear passenger belted in tightly could get choked if you lower the top into its well.)

Short answer: Firebird rear seats are the same width in coupe and convertible — both had rear armrests. (The “convertible seats are narrower” idea comes from Camaros, where the coupe had no rear armrests and a wider seat, except fold-down-equipped cars.) Bottom line: if the car has rear armrests, the seat is the correct Firebird width for either body style.

Short answer: No — Custom interior did not automatically include custom seat belts. Belts were a separate option from the interior (as were shoulder belts). Members have Custom-interior cars with standard belts and Standard-interior cars with deluxe belts.

Ordering deluxe belts also didn’t mean you got shoulder belts. The rarest combination would be a convertible with deluxe shoulder belts.

Short answer: The 1968 Custom Trim Option is code 554, and the trim-tag style number tells you what your car has. Note that the Custom Trim Option (554) and the Custom/Deluxe interior are separate — you can have the option with standard interior.

1968 Trim-Tag Style Numbers
Coupe Conv. Meaning
22337 22367 Standard interior, no Custom Trim option
22437 22467 Standard interior, with Custom Trim option
22637 22667 Deluxe (Custom) interior, with Custom Trim option

Custom Trim Option (554) included: deluxe wheel discs, deluxe steering wheel, molded-vinyl door and quarter trim, vinyl-and-weave seats, roof-rail moldings, wheel-opening moldings, instrument-panel grip (grab bar), pedal trim, and dual horns. It also came with different (longer) window regulators.

Speculated as included (not confirmed): 160-mph speedo, “BIRD” emblem on the glove-box door, custom/deluxe seat belts (brushed-metal buckles), the small white “BIRD” etched on the front side glass, interior windshield A-pillar moldings, and wheel trim rings (when ordered with Rally II wheels).

Any of these items could be ordered individually on a standard-interior car (22437/22467) — except the deluxe interior itself, which defines 22637/22667.

Short answer: The 1968 Custom Trim option (554) included: Custom seat covers (Morrokide + stitched knit vinyl), custom molded door and quarter trim panels, the assist bar above the glovebox, dual horns, deluxe wheel covers, deluxe steering wheel, custom pedal trim, front & rear wheel-opening moldings, drip-rail moldings (coupes), and windshield-pillar garnish moldings.

The RH sideview mirror was not part of the option. Everything in the package could be ordered separately on a Standard-trim car except the custom seats/trim panels and the assist bar. (And contrary to a common claim, the etched “Bird” front-side glass was not tied to Custom Trim — many original Standard-trim cars have it.) More on FGF.

Short answer: Deluxe (Custom) vs. Standard belt buckles:

  • Deluxe: brushed-chrome metal buckle cover; the latch (“spade”) has a narrow slot.
  • Standard: color-keyed plastic cover; wide latch slot.
  • Button emblem: 1967–68 Deluxe used the Fisher coach emblem (black); 1969 and later used the GM Mark of Excellence (blue).

Members’ measurements differ a bit: one cites a 9/16″ (Deluxe) vs 1-1/8″ (Standard) spade slot; another, measuring an original 1968 Deluxe set, gives the buckle’s latch slot at ~2.1875″ wide and the male latch slot at .50×.625″.

Mystery: some Firebirds (e.g., a documented 1968 RA I convertible with original date-coded Deluxe belts) came with Deluxe belts not noted on the paperwork — another unexplained one, like the “Bird” glass.

Bulletin 68-I-35 — Pontiac Motor Division Dealer Service Information Bulletin, Section 2, dated January 31, 1968. Attention: Service Manager.

Subject: Soiled or Stained Seat Belts.

Short answer: Clean soiled or stained seat belts only with a mild soap and lukewarm water solution — volatile cleaners and redyeing both weaken the belt fiber and must not be used.

Soiled or stained seat belts should only be cleaned with a mild soap and lukewarm water solution. Use of volatile cleaners could remove color and weaken the fiber.

Note: Under no circumstances should seat belts be redyed, as this could also weaken the fiber.

This is a transcription of the original dealer bulletin for easier reading and search. The complete original scan is shown below.

Short answer: The fold-down seat bottom is the same as the fixed seat. The top portion has no real cushion to redo — just some cotton and burlap over the springs.

Short answer: Headrests were optional on 1967 (code AS2) and 1968 (code 571). For 1969 they became government-mandated — in two styles, straight (early, same as 1967–68) and curved (later).

The 1969 upper seat frame is the same as 1967–68, so a 1969 frame is the easiest way to add headrests to a 1967–68 (use the padding and cover for your model). Note 1969s built before 1/1/69 still listed headrests as a charged option — they all got them, but the price sheet didn’t make them standard until then.

Short answer: Headrests (head restraints) were an option — here’s how they show up across the documentation (note the sources don’t fully agree on the code):

  • Billing card/manifest: 1967 = code 572; 1968 = code 572; 1969 = nothing listed.
  • Sales manual: 1968 head restraints = code 571, $52.66.
  • Body tags: 1967 has trim codes (Z = buckets without headrests, Y = buckets with headrests, H = standard bench); 1968 and 1969 references have no headrest body-tag code.

Short answer: The seat frames are the same for 1967, 1968, and 1969 — the difference is the padding (1969 is slightly wider). So for a 1968-correct headrest seat, use a 1969 headrest seat with 1968 padding and seat covers.

Short answer: Trim code 260 is “Parchment” in both 1967 and 1968, but the shade differs — 1967 parchment is basic white, while 1968 parchment has a pearl look. The factory trim albums call both “Parchment”; catalog companies rename the 1968 shade “Pearl” to avoid confusion. So your tag reading Parchment is correct.

Short answer: Correct — a 1968 parchment interior (seats and panels) came with black lower carpet/door trim and black nylon-blend loop-pile carpet, and (per member feedback) black dash, dash pad, visors, and kick panels. So your two-color scheme is original. Source: 1968 Pontiac Trim & Accessory Album and the 1968 Pontiac Sales Album.

Short answer: The fold-down rear seat was an option on all 1967–69 Firebirds/Camaros (UPC #604/A67, ~$42.13 in 1968–69). Many components are reproduced (latch, catch, brackets, knobs, carpet, partition); used assemblies run ~$175–350 (get all the parts). Desirable but not actually rare.

It was a sales dud because it didn’t open into the trunk. Available in both body styles; the 1967 differs from 1968–69 (the 1967 used retainer clips that could release and fold on a panic stop; 1968–69 added a right-side latch notch). You’d need the latch/brackets, the cardboard backing, and the track it lays in.

Short answer: Push the bottom cushion toward the rear of the car ~1–2″ to unhook it from the two floor brackets, then lift the front up and out — that exposes the screws holding the seat back.

Technique: Slide the front seats forward, climb into the back facing the rear with your back against the front seats, and put your hands under the rear cushion. Push the cushion straight back ~1–2″ and, while holding that pressure, lift the front of the cushion ~1″ and ease it off — the front hook has a large lip. There are two floor brackets, one near each side. Do each side; if one side won’t release, re-seat the side you freed and do both together, or work one side at a time. If a side is rusted together, free it before forcing.

With the cushion out, two large screws (through wire loops) release the seat back. (Also shown in the Fisher Body Manual — and look for your build sheet while you’re in there.)

Short answer: Leather (code 281, Saddle) became available on the 1968 Firebird on June 6, 1968, only with the Custom Trim option and only in that one Saddle color. It’s a very rare option — documented on only a few 1968 Firebirds in the Registry.

On the Firebird, the seat faces are leather with expanded-Morrokide (Madrid-grain vinyl) sides; door panels are faux leather grain; the dash and carpet are gold/tan. (For 1969, Firebird leather was code 293, gold — reportedly ~54 cars built.) Leather is one of the rarest Firebird options.

Bonus detail from a member’s parts book: some 1968 Custom interiors without knit-weave inserts came in “first type (grained vinyl)” vs “second type (knitted vinyl)” — only on a few colors: Teal (255), Turquoise (256), Gold (257), Parchment (260, and 275 bench).

Short answer: The plastic buckle cover just snaps on — gently pry it off from the sides (pry the rear portion first, not the end where the male latch enters, or you’ll snap a retaining tab). Then you can feed the belt up through the metal bar to make a big loop for cleaning.

Inside, the knurled bar should have tab ends that slide in side slots; if they’re seized, free them with detergent soaking or light oil and clean off the rust. Soaking the loosened belts (some even use a dishwasher) loosens old dirt; finish by scrubbing and sun-drying so they come out soft. You can repaint the plastic buckle covers before reassembly. Keep the white date tags near the anchor if you want originality.

Short answer: Soak and scrub the belts, then sun-dry them:

  1. Remove the belts from the car.
  2. Fill a bucket with scalding-hot water and add quality car-wash soap.
  3. Soak the belts (don’t let the water go cold).
  4. Scrub each belt end to end, front and back, with a soft brush — change the water once or twice if dirty.
  5. Rinse with a hose and lay flat in the sun to dry — this is key: air-drying out of the sun leaves them stiff, while sun-drying makes them soft and brings the color back.
  6. Blow water out of the buckle mechanism with compressed air (or a vacuum run in reverse).

Short answer: The Fisher Coach emblem was last used on 1967 belts. For 1968 (and later), the latch button reads “GM Mark of Excellence.” So a Fisher Coach emblem is correct for a 1967, not a 1968.

On 1968 belts, the latch housing was metal on Custom belts and plastic on Standard. (As always, expect exceptions from production errors, shortages, running changes, and carry-over builds.)

Short answer: 1968 and 1969 belts are the same except the date stamp on the white manufacture label at the belt end (only matters for 100% originality). Note 1969 coupes used shoulder belts with extra buckles on the tunnel side.

To find the anchor points after a floor-pan replacement: look under the car at the driveshaft tunnel for the seat-belt nut (welded to a large oval plate) and push a small nail (not a drill — a drill can snag and unravel the carpet) up through the carpet to mark it; the door-jamb anchor is under the sill plate with the carpet rolled back. Note: sometime in 1968 the buckles switched from plastic to metal (once thought to be standard vs. Custom trim).

Short answer: Not the same. 1967 used the same seats (dielectrically molded panels with 1″ ribs) for both Standard and Custom trim. For 1968–69, Custom trim used knit-weave vinyl, while 1968 Standard reused the 1967-style molded seats; 1969 Standard used the molded panels but with wider side bolsters.

Short answer: The seat-mount pedestal is two spot-welded pieces (an outer pedestal and a smaller inner brace, which also welds to the floor) — remove them separately, since you can’t reach the inner brace’s welds with the big piece on.

  • Drill the spot welds on the upper rocker by the door jamb first (minimizes damage where the new floor pan welds in), then unbolt the rear subframe bolts (soak the bolt top through the pedestal opening with penetrant overnight) and cut around the pedestal to pull it.
  • The frame-mount bolt’s nut is captured in the inner brace — you’ll eventually need it out (soak in penetrating oil a couple of days), but not to remove the upper piece.
  • Fit the new pan, cut the frame-bolt hole, bolt the pedestal down to spread the load and ensure a tight fit, scribe the pan, trim ~1/2″ below the line, weld solid, and caulk underneath. An Eastwood spot-weld cutter leaves half the weld for alignment when you MIG it back.

Short answer: Firebird seat belts are the same coupe or convertible — the only difference is Standard vs. Custom (plastic vs. die-cast latch cover).

Some very early 1968s with Standard belts used the die-cast latch. Sources: used belts, restoration services (not cheap), or swap meets (repros were coming). Originals have a date code.

Short answer: Vinyl dye works well on seats too (the ads omit them, but it’s fine), and going from faded parchment to white is easy since you’re not covering a dark color.

Skip the spray cans — have an auto paint-supply store mix the dye (by code or matched to a sample) and shoot it with a conventional spray gun. It’s heavily pigmented and covers in two coats. Follow the pre-clean/prep instructions carefully; the result looks like-new.

Short answer: Good foam padding and an air hog-ring gun make the job easier (especially one-person). Heat the vinyl first — set it in the sun or tumble it in a dryer (in a pillowcase) for a few minutes, and keep a hair dryer handy for spot-heating.

Put plastic trash bags over the seat foam so the covers slide on easier, then reach up and rip the bags out when you’re done.
