Here are some pics of the stretch job. Most of the body work was done by Matt Ballard, including the paint. The hardest part was moving the fenders rearward 6-1/2". The outer fender was cut out, and a piece from another 'Runner spliced in in front of it. The back half of the inner fender was moved back, and some sheet metal was grafted in to fill the gap, as seen in the picture. Once all the welding was done, the whole thing was fiberglassed to fill all the cracks and stuff.
For the spring hangers: Use the stock hangers for the front of the spring, and 56" AllPro rears. Move the shackle hanger back as needed. You will get less lift this way, since usually with the longer springs you would move the front hanger forward and down. So, a 5" spring would only give you 4" of lift if you do it like I did.
Since the rear shackle hanger would have ended up halfway off the frame for me, I welded a piece of 2x3" (3/16 wall) tubing inside the framerail, and extending back a few inches. I also used another piece of 2x3" tubing to drop the hanger a bit to give me more lift.
