An airride kid for a 2wd 1/2 ton 72 pickup will be the same (assuming your Jimmy is a factory 2wd truck.)

No bolt in roll cages that I can think of. Most of the roll bars of the era are more for looks than actual protection. S&W Racing used to make a kit, but it still required welding.

You'll probably get some heat for wanting to put a cage in a 2wd on air ride. Cages look better on the lifted 4wds (IMO), but it is true there is little safety with these rigs if they roll.
