    According to the part book for “K” models, they were a neopreme seal.
    I went ahead and installed the CR seal I had on hand.
    I found that the seal bore was “out of round” because the thin
    bore shoulder was dented in slightly in a part lifetime.
    I did a little hand work with my “de-burrer” and finally
    got the seal in.

    Prepare to be boarded!
