one thing Eric talked about was using a D50 spindle and hub since you could get them for dirt cheap. but i don't know what that means for brakes.
i used the TMR 3/4ton caliper bracket for GM d60. however, the dodge hubs i used have a different rotor offset vs the spindle flange. i accounted for this by actually mounting the TMR bracket to the back side of the spindle flange. had to cut the bracket to fit over the axle tube and only used 4 bolts then. it's about 1/16" off from perfect, but the caliper slides don't care. on the TJ i did make a spacer, but not on the YJ. you'd have to figure the difference for the different flange thickness if doing similar to me.
