Lots have start them not many finish. Got to 4btswaps.com and read a bit you will most likely be deterred after that lol. I was about to pick up a bread truck with a 4bt in it but my source of cash fell through though and I was going to just sit on the 4bt till I had 80% of the check list on 4bt swap forum. There are 4bf swap kits for jeeps, but really nothing for our trucks and most guy on the 4bt forum say to put the 3.3L 4bt in a small truck like ours (i believe its a japanese version or used primarily elsewhere in the world) instead of the larger 3.9L. The 3.3L is pricey so the 4bt swap guys say. Hope that helps a bit.
