Alright here is what ive got. Im swapping my 8 lug outers for 5 on 5.5 outers on a 79 hp 44. I really want to retain my steering knuckles from the 3/4 ton axle since they are already flat tops and are beefier than any other stock knuckle out there for a 44. Here is my dilemma, i cant find a backing plate to run half ton calipers with this spindle bolt pattern. Its bigger than any 44 spindle pattern ive seen. I was hoping a ford dana 60 would be close enough and i could just buy the conversion backing plates that allows you to run a chevy 3/4 and half ton caliper. I hope that makes sense lol.
