Recommended posi rear end?

How much power you plan on putting out? More importantly do you plan on running tires that will hook up? If not, then most likely a 8.25 sure grip will be just fine. If you plan on hooking up some power than 8.75 rear end should be the minimum you should use.....it all just depends on what your trying to do.

....oh and mopars don't have posi, they only have sure-grip, a posi is a chevy diff. Lol:toothy10:
