Awesome, Thank you I wasn't aware that Doctor Diff made these kits. A guy responded here with the spindles but now I cant find the bearings needed online. Im thinking of just doing the Doctor Diff route sounds easier and straight forward.
I would agree with using the ‘73+ spindles. The ‘70-72 B/E body spindles are basically identical except for the different wheel bearings, but that wheel bearing makes them a 3 year only part.
The 73+ spindles have brakes and wheel bearings that were used on Mopars all the way up into the late eighties, and are widely reproduced. The DoctorDiff parts are all OE reproductions, so, you can get rotors, calipers, bearings etc. at the local parts store if you need to.
