torsion bar keys how to?

how do you install new torsion bar keys to level a 04 chevy colorado, and how hard is it?  

I did my 2500 hd in about 1 hour and a half i borowed a ball joint toll and it was so simple I was i couldn't beleave  it i stuck a nut driver in the big hole of the ball joint tool to keep it from slipping off the torsion bar frame work I did the one from oru with 4 shocks they even sent me 2 " longer rears I just asked them to send them in the comment section when ordering no extra charge I also installed air bags in rear and two inch spacers under bags with on board air the spacers needed extra hard where because I need a bolt that I could thighten with an allen wrench had compressor mounted and wired before hand hole thing took me 12 hrs with two trips to hardeware store all because of the bag spacers I ended up having to up size bolts on bag spacers because stock size hard ware was not available @ 5:00 on a sat so I just drilled spacers and tapped but klems a tractor supply and everything else store had grade 8 tapered head allen bolts so I was very pleased to have truck back together in one day with just a little more than the hand tools I use As an electrician the spacers used the bolts the bags use to mount bag to bottom plate and then give you hex head so bottom mount for bags didn't fit flush on bump stop plate the way I liked so that the only reason for modfying spacers truck sits on 285-75-16 on stock rims still plan to buy new leafs and only use bags to keep from wearing out rear springs and want to run 35" tires or 36" tires if I can need to do researsh but cofident I can run 35" but want wider rims first since I carry piggy back camper air down but since lift I put on factory mud flaps so might need to modify those for tires here is a link to myspace with pics of truck and camper

sorry but first time I been able to thread about my lift high light the link and copy and paste it to your address bar to open pics I gained 3-4" at push bar and 3 inches all the way around and I marked my adjusters and re installed them exatly where they where and have plenty off roomm to adjust if I had millions of dollars to by front shafts  but that is about the easyist project I could have done just spray the shocks and torsion keys with plent of lube or nut off I did mine Wednesday and Friday a didn"t move truck then worked on it on Saturday  

Has any one done an gmc or chevey 01 body styled Hd with 2" lift and anything bigger than 35" tires
