    Wouldn't put money into a 7.5 diff, Okay if you already have one and get a used right hand axle to put on the left side and narrow yourself. Only use for a cruiser, any performance you'll probably break it.

    It is a lot better to go to the local pick and pull, find a Ford Explorer 8.8 rear diff. these diffs are quite affordable and almost as strong as a 12 bolt. The newest ones have rear disc brakes.

    PS - Do a search on the web for Explorer 8.8 diff. You'll find plenty of info on them.
