rear end question

[gasmn1620]

So 5x5 lug wheels are not the easiest to find. Going 6 lug would open up the options a lot. Anybody swapped in a complete late model rear end under a square body. That would get me rear disc brakes and 6 lug in one shot. Mcgaughys makes a BBK tthat has 6 lug rotors instead of 5 lug.... and I need new everything up front aanyway.
