Rather than trying to piece together your own lift, you're better off buying a complete kit. Talk to the different lift manufacturers to see what they reccommend. A few phone calls will help tremendously.
I agree in the end it will be wiser to buy a kit based on your needs. Try looking at 4wd.com they may have a kit there. If you have the time and the tools (welder) then you might want to research the other did it themselves kits and start in that direction.
