64-67 A body rear ends

[pontiacgp]

I have a 67 version of the A body rear ends. The rear end is wider then the B body rear but the lower control arms are closer together causing a problem with the lower control arms. I have the UMI lowers custom made with the Roto Joint to solve that problem. JBrue has the 68-72 version which is 2" wider than the 67 version so I don't think he had any issues with the lower. Here's a few pictures to show you the angle the Roto Joint sits at in the UMI lowers at the rear end.

I have the 68 and my stock lowers fit right in.

I thought that 68-72 version would fit. JBrue helped me out alot and he never mentioned any issues with the lowers. I did get the bolts in the stock lowers but it didn't look too good. UMI has the lowers with the spherical rod end but I wanted the Roto Joint as I have the Roto Joint on the conversion uppers. UMI modified the tube for the and added the Roto Joint for a very minimal cost and took no time to get them done
