    Ozzie,

    Thanks so much … that is a big help!

    It looks like Scott-Atwater may have been using Chicago Rawhide (CR) as their supplier, as upon close inspection of the seals, they both had CR numbers stamped into them. I typed the numbers in SKF‘s online CR interchange tool (https://www.skfextranet.com/crsealsfinder/ ) and was able to find current SKF part numbers, which I also cross referenced to Timken. Here were my results:

    Drive Shaft Seal
    SKF 6903 (original CR 11120)
    Timken interchange = 450009

    Prop Shaft
    SKF 10049 (original CR 1831)
    Timken interchange =450593

    With those and your Sierra numbers, I now have some options to go shopping! It’s nice that there is some hope for guys looking for Scott-Atwater seals if they were using CR seals.

    Thanks, again, for your help. Always good to hear from you, too. (This is my first post in a long time.)
