this was the same plan i had. i decided to turn the project around and do the front first but the rear will come into play later. i got a donated frame and cut sections out of it and premade inserts. my original idea was for a foot of extension. as i photoshopped the various lengths the plan got shorter and shorter. 116 is incredibly long. you have to watch out for the limo look. i think mine will be in the 6-8" range. people suggested just getting an unlimited tj or compcutting. i didnt want the long rear and the wheelbase stretch itself was only a byproduct of stretching the tub and not the goal in itself. right now im stretched 5" in the front so i have to be careful to keep the wheelbase within reason for the tire size.
