If I was building a Dart for my wife it would have a Dana 60 in it. I had to replace the entire driveline of our '71 F100 4wd because my wife blew up the single speed Dana transfer case doing burnouts with the old 35x12.50" tires. It got an NP435/NP205 combo out of a '77 F250 after that. It was pretty wild watching that FE390 light up those 35's!
