Have you heard of a machined Wagoneer drum working for this application?
No, I haven't been involved in that specific modification, but we pretty routinely modified drums, caliper mounts, and rotors for racing applications without any serious problems. One of the Super Truck series vehicles I worked with at the Nashville fairgrounds track had the old style 4-piston rigid-mount Cadillac calipers on it, and I modified it to run a floating caliper setup from a Monte Carlo, even made the caliper mounts from scratch. Brake parts don't know what vehicle they're on- - -as long as everything fits and is aligned properly, it should work. The specifications on the two drums you illustrated are so similar I can't see any problem making the substitution as long as a competent machinist gets involved. As always, "Measure twice- - - -cut once!" Good luck!
