If I recall correctly I think it is a 8.5" 10 Bolt rear end in mine.... so yours may or may not be the same since it is a 9C1.

I believe the B-bodies of that age were available with an 7.5" or 8.5". Since yours is a 9c1 it should have the 8.5, but I would double check it

Heres a pic of an 8.5, the 7.5" has indentations on the "lugs"

Search Ebay for a 94'-96' Impala SS rearend, it will fit without any mods being required. I have an 80' 2-dr Caprice Landau that I am currently swapping in an LS1 and I already have the rear set in place.
