Keep in mind, that truck is a 72 which has the wider (by approx .750 each side) rear 12-bolt. That would explain why they fit w/o spacers/adapters vs. the shorter housing from a 6x-70.

Opposite.... more back spacing within the same width of a wheel means less 'lip' on the outside. Less BS = more lip.

20x10 will fit in the rear for my truck, I was just thinking of the rotating purposes for the 20x8.5 all the way around, but if it won't look right, then I would rather go with staggered.

I like staggered sizing front to rear. I've never owned a vehicle w/the same width F/R thus have never rotated tires. If you don't mind the same size 8.5" front & rear, they should work w/o spacers. The 20x10's appear to work for the rear of 71-72's w/o issue looking @ the pic of Benji's truck (nice truck @ that).
