You will get all kinds of opinions, and here is mine. I have a 69RR and purchased the MP front disk brake power conversion kit, an upgrade from the standard. Basically they use parts from mopars from the 70's, so no problem getting replacement pads, parts, etc. I used them as they claimed to be the largest supplier of model specific kits. My kit bolted right on, EXCEPT I had to fabricate some lines to tie the combination valve to the system. That was an unpleasant surprise. Otherwise the kit was complete, the quality is good, the tech support was good, and the system works well. It also took the entire weekend to install the kit which was longer than I expected (I am not unfamiliar with automobile brake systems, in fact am studying for the A5 exam). Also, I bought the system for a car that I would like to drive daily, so it has a single piston caliper (they have a 4 piston and other upgraded versions as well) which I like as it's easier to service. Overall, I would recommend MP.
