Dealer Service Information Bulletin 68-I-42 – Replacement of Rear Door Locks – 1968 Pontiac
Bulletin 68-I-42 — Pontiac Motor Division Dealer Service Information Bulletin, Section 2, dated February 5, 1968. Attention: Service Manager.
Subject: Replacement of Rear Door Locks — 1968 Pontiac.
Short answer: On 1968 Pontiacs with production date code 10A or earlier, the rear door lock and remote control lock rod must always be replaced together as a matched set using Service Kit Part No. 8700036 (RH) or 8700037 (LH); individual parts may be used only on units built after date code 10A.
After the start of 1968 production, Pontiac’s rear door locks and remote control to lock rods were redesigned to provide easier door lock operation. Individually, early and late production parts are not interchangeable, and initial production parts are not available for service parts.
On Pontiacs with production date code 10A or earlier (located on the Fisher Body plate on the firewall), it is essential that both the rear door lock and remote control lock rod be replaced at the same time in the event either one requires replacement.
Service kit Part No. 8700036 RH and 8700037 LH [M] (Gp. No. 10.473) includes both the lock and remote control rod. Individual parts can be replaced only on units produced after date code 10A.
Note: Prior to installing the remote control attaching bolts, hold the control in an installed position to determine if the connecting rod is entering the remote control at the proper angle. Rods entering the remote control at incorrect angles will prevent either the top or bottom of the control from fitting flush to the inner panel, and cause sluggish operation of the remote control handle. If the remote control is being held out at top or bottom, rework the rod while attached to the lock and remote control assembly by rotating the top of the remote control assembly inboard or outboard.
