Rear end swap '90 12 bolt into '71
My cousin has a low mile 12 bolt posi 3.73 rear end from a '90 454SS truck for sale and I'm thinking of replacing my factory open diff 3.73 rear. Does anybody know if the width is compatible with the factory '71 1/2 ton 5-lug? If it is the same or very close, would I just be looking at adding the coil spring perches / removing leaf perches?
Thanks in advance!
