I just completed a rusty hope disc brake conversion on my 51 Windsor Deluxe. I made it work with advice from Charlie. I think that any install on these cars will have issues, here were my challenges. 1) His brackets come as bare metal, be prepared to paint them for corrosion protection. 2) I drilled and tapped my spindles on the car, if I were to do it again, I would have removed them and done it on a Bridgeport or drill press but it did work the way I did it. 3) The spacer he supplied was incorrect for my spindles and allowed the rotor inner face to contact the spindle. I had to fabricate additional shims to gain clearance (0.050"). One of the bolts he supplied was too long and protruded through the spindle to the rotor. I made thick washers to correct it. 4) He specified to buy banjo bolts yet they also came with the calipers he specified so it was money wasted. 5) the dust caps he specified did not fit the rotors he specified. I had to buy Dodge Diplomat caps that were correct and even then, I had to trim 0.100" off because they contacted the outer bearing race before they seated against the rotor hub.
