UPDATE: Found a guy about 30 minutes from home selling a set of rims off his old 68 1/2 ton. 6 lug and look to be just perfect (plain steel, nothing fancy for my truck).
Only wanted 50 bucks for the set of four, so, had to say yes of course.
Now, to find some tires for it. Any recommendations for what best runs on 1968 15s?
