I have come across an HP44HD out of a 78 F-250 that is 8 lug. I want to know if I can keep the 3/4 ton knuckles and switch out the spindle so I can run 5x5.5 bolt pattern? Or what would I need to change out if I wanted the 5x5.5 pattern with the 3/4 ton knuckles? I like the fact the 3/4 ton knuckles are already flat top, use 3/4 ton brakes and uses bigger ball joints. Let me know your thoughts. Thanks.
