'93 have the single piston/"slide" calipers. So,
@smccatv really wants to start by upgrading his Ranger's knuckles to '95-'95 ones to get bolt in calipers (doesn't require newer i-beams, but you would want to replace ball joints while you had it apart). Then integrating adapter between knuckle and caliper becomes a bolt in process (An adapter for "slide" calipers would be a work of art though).
I've done the machining on hub/adapter myself, but due to product liability reasons, I won't commercially do it. And my adapter was hogged out of a single block of steel as I don't trust aluminium on brakes where the original design wasn't for that material. Saving a pound wasn't worth it on 2,500lb truck.
@smccatv You probably want to run spacers with most (all) Mustang rims, so the bearing cap doesn't interfere with the rim center/the offset is correct - you can see
@Rangeritus is. (Ranger rims are 0-12mm offset, Mustangs are 30-40mm).
