NCridgerunner..1971 is close enough to 1970....What wheels did you use, especially in the Front? I have later model wheels in the back outer - the inners are the original with the outer ring, as they are "Hub Centric" I tried to put the outer rears on the front & found they go to far in, against the control arms, never even got to the lug studs. What I have in the front are 16.5 from most likely a mid 70 ies 3/4 ton. Not "Hub Centric" the taper in the wheel is the strength from the lug nut.The guy who had the truck before me did all the wheel switching, I'm trying to get it back with Radial tubeless tires...I just need to know what wheels to use....Thanks
