I couldn't find the solution to this problem with a search of this forum. The drivers side door lock has a shaft that goes through a plastic part that interlocks with the rest of the locking system. That plastic part broke. I can't find this part in the FastLane parts list. The local junk yard had 1 123 body style in stock and he broke the part trying to get it out. The passenger side will not work because it is a mirror image. Where can I get this part?
