Anyone tried this rear disc kit before?

There are multiple ways to do this. The right stuff kit does not have Mopar 73+ front disks, the PST kit does which is why it also has spindles and UCA’s because you need the large ball joint for the 73+ spindle.

Nothing against PST, but you can get the full 73+ front disk conversion and everything in that kit (if you want) from DoctorDiff too. And you’ll get it with better bearings and seals, can add or leave any of the parts you don’t need, and get a rear disk kit that will allow you to keep the tapered bearings in the rear.


The main reason im looking at a full kit is i dont know exactly what i need. I know i have a 71 duster with drum brakes and i want discs, so that kit supoosedly has every single part i need. Is the doctor diff one cheaper if you just buy all the individual components piece by piece vs grabbing an entire kit like this?
