Floor Pan Replacement (revisited)
Short answer: The cleanest way to replace a front floor is to drill the spot welds along the top of the rocker, cut the pan across the front, back, and tunnel, and remove the seat pedestal still attached to the old pan — then separate them on the bench. Use a spot-weld cutter on the braces and an air chisel to rip out the old floor.
Key tips:
- On a convertible, brace it and support it evenly side-to-side before cutting; mark the alignment of the seat support and frame brace before removing them (measuring afterward is very hard).
- Inspect the front floorboard supports — they’re often badly rusted and may need rebuilding with heavy-gauge steel.
- Replacement pans come two ways: rocker lip folded “up” (easier — weld from the top) or folded “down” to match the original (needs welding from underneath at the pinch-weld). The turned-down style was sold by C.A.R.S. Inc. (714-525-1956 CA / 248-398-7100 MI, www.carsinc.com).
- Don’t remove the spot welds along the bottom of the rocker — air-chisel along the 90° bend instead, then hammer the old edge flat and pre-drill the new pan’s lip to mimic the factory spot welds.
- Mock-fit the pan and set the pedestal in place with self-tapping screws (pre-drill the outer layer) before welding. Lay the new pan over the lower-firewall lip so you can’t set it too low. Use the pre-drilled subframe-bolt hole or the tunnel-side bend as reference points; trace the pan and never cut above that line.
