1957 DeSoto 8 3/4"

I bought a truck bed trailer with one of those old tapered axle rear ends. The guy had torched off all the brakes because they were stuck and he didn’t have the means to properly remove the drum. It looks like disk brakes could be added just like it is... if you found a rotor that could slide on and fit right, along with some kind of caliper bracket welded to the housing. A guy I know does that kind of thing with Dana 60s in his rock crawling rigs.

There probably is no kit, you would need to fabricate and modify everything.
