Okay... I needed cheap lift for my 90 GMC 1/2 ton... so I did what any 16 year old (at the time) would do.... I cranked the torsion bars up and put some blocks in the rear end. I'm smarter now... I hate it and want it back to stock... how do I do it? I know how to do the rear end no problem, but how do I set the torsion bars back to their stock setting? Any help would be greatly appreciated.
