A: I think only Pacer fits Pacer, but for that kind of money, he could have it shipped to Randy's ring and pinion (maybe there's one closeby? http://ringpinion.com ) Any Jeep shops? Internals are the same as early XJs. From: Justin Shelton <justinshelton@xxxxxxxxxxxxx> Subject: rear diff needed for Pacer To: mail@xxxxxxxxxxxx Howdy: A friend of mine caught the AMC bug from me and just bought a '75 Pacer DL with auto tranny. It has a whine in the differential, and his mechanic says it will cost about $1100 to rebuilt! He was shocked and sad that his new toy needed so much money put into it right up front, so I told him to just stick in a used one. He is in South Bend, IN, and I do not know the local parts yards that have AMCs in them. Questions: 1. Anyone have a spare diff laying around they'd be willing to part with? 2. What other AMCs of that vintage share the same differential? I hope that Gremlins and Hornets use the same, maybe even the Matador?? Thanks, guys. - Justin
