i am just starting my restoration on my firebird as well but from my experience on other cars i can tell you take it all apart first. there is no way for them to get to all the tight spots to blast them otherwise. and if your restoring it you are going to want all new bushings, rubber, etc anyways. to remove the springs use a spring compressor you can buy at the parts store, but be VERY careful, lots of energy stored in the springs. not a hard job but just be careful. other than the springs everything else just unbolts off. to take the spindle off the a-arms loosen the ball joint nuts and whack the spindle with a hammer where the ball joint goes through until it pops loose or buy a pickle fork at the parts store also. my suggestion, take lots of pictures and bag and tag everything. hope this helps, take some pics and put them on photobucket for us to see!!!
