Has anyone tried or is it even possible to swap the rear disc brakes from a 94 or newer Grand Cherokee or Durango to the 8 3/4 rear in my 72 RR. What is involved in the swap, will it work and will I have any problems eliminating the electronics for the rear discs?

I am planning on doing a 11.75 front disc swap and keeping my power setup.

Any help would be appreciated!
