65' Cuda Drum to Disc advice

You have like 3 choices:

1. Factory Kelsey-Hays, 4 piston calipers, change lower ball joint, still retain small bolt pattern, different master cylinder.

2. Factory single piston calipers from a 73 to 76 "A" body, requires same years upper control arms (73-76), different master cylinder, change to large bolt pattern.

3. Aftermarket, Wilwood is one I can think of off the top of my head, there are a host of others. Other members may know of many more and list them.

Myself, I did the factory 73 to 76 route, it's easy. If the front end of your car has never been rebuilt in the past, this would be a perfect time. Also an upgrade in the rear wouldn't hurt; that 5.9 will make a mess of the 7 1/4 sooner rather than later. IF you go this route; factory single piston from 73 to 76, take the rear out of the donor car, which should be an 8 1/4, don't worry about gear ratio that can always be changed.

Good luck!
