not sure if this belongs in here or the lounge but I figure it relates more to the garage. I was at work earlier and there was a guy that came in to get some gaskets for his axle covers. he was driving an 80 model, one of the years where gm was changing axles so it brought up on the computer that it could have 10b fronts and either a 10b or 12b rear. the guy said its not either one of those so I go outside to look and see. come back in and tell him that hes got 10blts front and rear. he shakes his head no. so most of you have heard of the elusive 12b front right? well how about 11 bolts front and rear. I told him that if he had 11 bolts front and rear I would buy the gaskets and change them for him. he ended up going to autozone cause we didnt have any 11 bolt diff cover gaskets.
