Yeah, don't cut your springs. You can only cut so much before it affects ride comfort. You can cut your bumpstops or buy new shorter ones but, again, you're only gonna be able to take it so far and the ride'll be rough.
There's tons of aftermarket stuff for lowering 60-72 trucks. Get yourself some NEW springs that'll lower you a bit, then add drop spindles (while you're at it, upgrade to disc brakes) to get even lower. Don't forget all this will have an effect on your driveshaft angle.
Pick up any of the classic truck mags. There's tons of ads for parts to help lower your truck.
