    Diff numbers ???

    Can someone tell me how I can cross the numbers on the white tag on the diff to something. I can read the ratio but the other numbers aren't part numbers
    that I can cross in Realoem. I trying to do a diff swap and what to be sure of what vehicle it come out of somehow. Any help would be much appreciated

    thanks

    You probably can't even trust those numbers, the tags are only bolted on so they are easily swapped or removed etc. There is usually a physical difference between the small, medium and large case diffs, generally the back cover is a bit different on them all at a minimum

    the tag I'm referring to is the white sticker on the top of the diff that they all have. I suppose they can be swapped as well. The sets of numbers
    on that tag have to relate to something?

    I do not have what you are looking for but this is were the various ratios come from.
