AAM 10.5 out of a 2003 Dodge Ram 2500 into a 74 dart with a 904. Splines = 30 (27 in the 904) wheels are 8 bolt (want to convert to 5) but it has 4.1's and lsd and is reasonably priced. I don't know the exact difference in width as I believe I should measure the actual axle for that number but Id bet it's too wide, so chop or buy axles that will fit? Are these any good? Has anyone done this? Am I stupid for even asking? I'm just curious at this point, not going to waste money on something that won't work...... again......this week...:-D
