I am in the middle of putting a Heidt's IFS with power rack & pinion steering on a 55 Chevy pickup. It is a well built kit, fits nice, and has good instructions. You can also find online articles with pictures and instructions for installing it. Beware that the kit with the stock height spindles will lower your truck by 3 - 4 inches. So the "dropped" spindles will lower it a lot more. You can talk to the Heidt's people direct and get a lot of help. The lowest price I could find (not cheap) was Tims Hot Rods - he's on Ebay. There are lot's of other manufacturer's out there - Fatman, Total Cost Involved, Chassis Engineering, etc. Do your homework before buying anything like this.
