Corvettes, 49-64 chevy's and mid size GM's up to the front wheel drive, S10's, Camaro/Firebird, to name a few, all use 5 on 4 3/4" BC. The Caprice started the 5 on 5 BC as far as chevy's are concerned. The big GM's like Roadmasters, Cads, 98's, etc had 5 on 5 for years (my 37 Buick has 5 on 5). S10's are probably the easiest to find anymore.
