Front.
22x9's will easily fit in the rear. I would measure for verification, but 5.5"bs should be the magic number for the 72 model rear (if everything is centered correctly). 20x10's would be a tight squeeze in factory 67-72 tubs on big-time drops. They'll fit but are going to be close on one side or the other. I used a 5"bs for my 68 & mini-tubbed the tubs < 2" to make sure they wouldn't buzz the outer edge & allow for plenty of clearance on the inner tub. A 72 might not need the mini-tub because the slightly wider width changes the bs needs.
I highly recommend grabbing a plain old steel wheel of a known size & use it as the baseline for determining what will work best on YOUR truck. Once you know the dimensions/bs of your baseline wheel, it's simple addition/subtraction to figure out what you'll need.
