As usual I have a question. I have the opportunity to get a Chevy 12 bolt rear out of a 66 Impala will this fit my 66 skylark. with a 455 and a th400 tranny. Thanks in advance Elliott
Nope, pretty sure it has to be an A body, which an Impala isn't. Why are you giving up on your 66 rear? It should be an 8.2 10 bolt with bolt in axles. Unless you are drag racing with a stout 455, and hooking it up, it should be fine
