Thanks for all the info. There is a lot more choices out there than I thought. I am still undecided if I am going to keep the sbp, which I have now, or, convert to the large bolt pattern.:D
I don't know your intended use of your car but if you already have the 8 3/4 rear end then you're well on your way far as strength wise. Switch out the axles (Yukon, Strange) and then do the front brakes... poof ... done. lol
