There is one issue I can see being a problem. while there is only 2" difference in the wheelbase, with the TF having the shorter wheelbase, you may find that the rear wheels will be too far forward in the wheel openings. In stock form, the AD trucks rear wheels are roughly 2" forward of center, so couple that on top of the wheelbase difference, you end up being 4" forward of center. Just something you might want to keep in mind during the conversion. You could try to lengthen the TF wheelbase to correct, or you could like a 3800 AD truck that's local to me is. The owner of this truck put the cab abd bed on a Blazer chassis, but shortened the bed and runing boards to match the shorter frame. It is noticable, but at first it's somewhat difficult to put your fnger on what's not quite right. Perhaps what you culd do, instead of shortening the bed, is to move the fenders forward a bit, and shorten the running boards accordingly. Not a lot, just enough to make it look good.
