74 power wagon dream truck...

Bolt pattern is all the same Chevy Ford Dodge...= 8 on 6.5” that goes well into the 90’s to early 2000’s. My 2002 Ram 2500 24v diesel is still 8 on 6.5 lug pattern.
I think Dodge had the largest center opening, swapping factory wheels ya gotta be careful. Aftermarket Wheels, they mostly all came with the larger center opening to fit the Big 3.
Okay now this is very Colombo like LOL...
My next question is the proportioning valve? I understand I'll probably get the master cylinder with the bigger front reservoir for disc brakes...
