How to install a body lift on 99 - 07 chevy/gmc 1500 trucks

I take you step by step on installing a body lift on a 2000 GMC sierra. This will work for 99 to 07 Chevy and GMC half-ton trucks. The kit I installed was from a junkyard, however, I have a link for those of you that don't want to wait for one to come up at the junk yard.
