THere is a chart that has already been printed it was in the Petterson's 4wheel drive mag, I have a copy at home I will take a look and see if I can find it. It out lines all of the tire sizes and what will need to be changed, lifts, steering arms, brake lines, you name it. I recently moved so I will have to do some digging.
In the mean time here is a lillte info I found on the net.
