Here is something I saw on e-bay http://cgi.ebay.com/ebaymotors/12-Bolt-Chevy-Rear-End-Housing_W0QQitemZ250140876321QQihZ015QQcategoryZ33 731QQrdZ1QQcmdZViewItem

I'm no expert here but will this work in a Camaro?

That is a '70 Camaro rear end. It is wider than the '67 to '69 rear end and the spring perches are about 3 inches farther apart. Looks like it has a lot of rust in it where the bearings would go. I wonder if the bearing caps are still in it.
