Oddly enough, I took a trip today to the local 4wd shop and they had a 2000 4wd sitting in the parking lot. They were nice enough to let me take a whole lot of pictures and poke around the truck a bit. Looks like the rear springs are the same and they mount to the same points and same brackets. The only difference I can see are the blocks on the axle, and longer u-bolts. The front of the truck is a different story. However the frames appear to be identical as far as the holes and mounting locations go. I am going to do the conversion and document the whole project from start to finish. I guess it is time to start finding some parts.
