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.
