About to start rear end swap... a few questions?

I am using the ones from my 8 1/4. From what I've read everything should swap over.

As far as U bolts and shock plates, I guess Ill have to find out when I get that fast? This is pretty much a rust free car so all the old parts are in really good shape. I thought I could just swap those parts over as well. However you guys think ill need a differnt size??

Thanks!
