We're looking to replace the door locks on the Pontiac and wondered if a regular replacement set from Original Parts Group would work? It seems like Superior used off-the-shelf parts, but we never know which shelf! I figure the doors, and probably the glove box locks will be fine, but what about the rear door? Will the trunk lock included in the set accept the existing linkage off the old one? Does anyone have a set with keys for sale? Thanks!
