A Body Rear End Options?

I put a 8 1/4 from a Volare which has the iso-mounts anyway so you can make any width for the mounts. Factory width for my 64 flange to flange was 53.2 volare was 54.34 so 1.14 inches wider is not to bad to split on either side so just a hair over 1/2 inch per side. I got the measurements from my now worn out Chrysler performance upgrades book. The best money ever spent.
