8 1/4 or 8 3/4 rear end

Seems the B body rear is longer and would need to be narrowed quite a bit. Looking for something with less work need. How much were you asking for it if I had to go that route?

I know 8.75's for an A body are hard to come by, which seems ill need to lean towards an 8.25
I tried to send you a PM but your inbox is full. I would like $600 for the rear end if you can do that. Ill post a link to it here
