i was wondering if any body had any tip or pics or facts on how to do a channal body drop for a 97 chevy 1500 truck

I beleive the latest issue of sport truck mag. has a how to on channeling that body style. That is what I want to trade my truck for! Later Tony from Norcal

i just bought a 1990 short bed 1500 and it came already frame droped and cab and bed was already off so i was wondering if or how many inches do i lift the bed or do i just cut it out and see how much the bed laying with the cab and then weld the new floor to it . But of course make sure everything is level right .Let me know someone thanks Roco
