Which rear end to use?

I always shim the c clips so there is no lateral play, basically have to because I have rear disk brakes and if not during turns the axels shift in and out and make the pads rub on the rotors.

I cruise all these posts and look for little pieces of gold, and that is a nugget worth keeping.
Thank you.
I'll be swapping to an 8 1/4 with discs from a Grand Cherokee as soon as I can.
Probably get it this winter and have it ready to go when spring comes around.
I'm considering the Powertrax product with 3:55 gears over the Suregrip since it would be easy to swap back and forth between a full locker and an open if needed.
