Thats weird the 7 1/4 that came out of my barracuda was 55.5 or so inches, the 8 3/4 I swaped it out to is the same width as the 7 1/4 and the 8.8 explorer axle I have is about 59.75" So I guess its closer to 4 inches wider. Do they make different width a body axles? Ive delt with a bunch of explorer 8.8s and they are all the same basic widthm so it must be the a body axles that vary.
