[Chevelle-List] rear end setup

[vmckague]

Guys , maybe someone can help me out. On my 64 El Camino I'm trying to find out what the rear end came out of. My friend says it not a 64 but an 80 model as someone has written 80 on the rear end cover with one of those yellow markers used in junk yards. It is a 10 bolt posi. I wonder where the numbers whould be on it and if I could find them how would I know where to look to find out what kind of car it came out of? He thinks maybe grand prix . Any ideas? Thanks , Vernon ACES# 05503
