if you've got a kick, the only mounts that use bolts are the two front ones under the headlights.
the rest should be studs, which are fixed to the body. i think a 1" should be ok with out other mods, but 2" or bigger, you either need to get some aluminium blocks made up and threaded, or do a budget lift and use box section.
the rear body studs can be removed and replaced with bolts if needed, but you have to drill a couple of holes out of the body.
everything else should be straight forward, unbolt body, lift body, put in spacers, lower body and bolt up again. in more or less words. just make sure you check fuel lines and brake lines when lifting the body, as you might have to lift the body a few (maybe 3", or 1" off the chassis) to insert the blocks. just take it slow.
