look on inside of back side, sand them down and youll find size stamped into them, also check inside between beads near the valve, youll find size somewhere stamped, all factory wheels have this, just look

6 lug 16" were factory available option in 67-72 years i know, im pretty sure 16.5" too for the 1/2 tons(5 and 6 lug)

wheels were narrower than you think back then, didnt see 15x7 wheels on the trucks yet, 15x8 was 73-up thing on the ralley type wheels and 15x6.5" on the vans
