im going through the same thing lol. i just bought a whole carrier / ring and pinion from a 2000 ford explorer. alot of fords have the 8.8 in them. rangers, explorers, f 150s just depends what gears you want. axles from 83-92 rangers are the same lenght as stock fox ones im pretty sure. 5 bolt .except there only 28 spline, and most diffs have 31 spline in them. if not anyone can correct me me by all means.
