So my Dad found this one at a junk yard by his house, on a late 70's early 80's wrecker. The guy will pull it for $500. Needs ball joints, and who know's what else, but I figure for $500 can't go wrong? I know it will need SRW hubs put on for my application, but is there more to converting this to SRW hubs than just the hubs/rotor assemblies? Not sure what its got for gears, maybe 4.10 for a wrecker application?
