You seem to know your axles. Why couldn't I convert my first gen Dodge 16.5 coined dually wheels to hub centric wheels on my dana 70 in the rear only? Since dana 70's were used in so many applications that weren't coined like Dodge ? Do you know the diameter of the Dana 70 dually hub without me taking the wheel off? I was thinking it was 4.75 I just couldn't get a 8×6.5 16 Ford wheels to fit hubcentric? Also its the 5/8-16 studs.
I wouldn't even know where to start giving advice on that. Sounds like might need to call a tire store and ask them. Most of the stuff I do is off-roading
