I have a 72 fj40, with a stock f engine, and a totoya 3spd setup. It is SOA(shackle reversed), otherwise stock. Heres the question. In order to swap in an SM420, I need: -sm420 -420 to 3pd tcase adapter -chevy clutch disk -crossmember -modify holes for shifters -adapt tcase linkage to mount on tranny -driveshafts I think thats it, maybe i forgot something. Let me know your thoughts/experiences and my mistakes. Open to all suggestions, but i need to put in 420 or 465. I need the gears. I will be flipping the rear springs at the same time and adding hypershackes to the rear Keep in mind, im on a very tight budget, because im only 17 and have a part time job and school. Appreciate any comments/suggestions.
