Front Disc Brake Conversion Confusion

sccachallenger said

Mopar Action featured a brake swap years ago that used your knuckle. You'd use the 11.75" factory rotor and use a 4 piston caliper. Not sure if it was early Viper or wilwood. Andy F might have been the source for the caliper bracket. Might be worth looking into as it uses stock rotors.

Yeah that is a blast from the past! I was messing around with disc brake conversions 20 years ago and that was one of the combinations I came up with. Somehow I figured out that the late model A body drum knuckle used the same exact spindle as the disc knuckle. A lot of people didn't believe me when I told them that including Eberg. But he quickly came around once he looked up the bearing cross reference info. Since a rotor slides right on it just took a little reverse engineering to develop a caliper bracket. I tried a few different calipers but eventually decided the early Viper caliper was the best (and coolest). It was a nice little conversion kit that worked pretty well but eventually Viper calipers got hard to find so I gave up on it. Cass redesigned it and made it better which is cool. I eventually upgraded my cars to 17 inch rims and 13 inch rotors but I still use Viper calipers.
