Hy DaOzTinman, I found two possibilities C/R 12530 = Napa NOS12530 $11.49 the dimensions of this seal are 1.250" X 2.063" X .438", the second possibility is C/R 21163 = Napa NOS21163 $12.49 the dimensions of this seal are 2.125" X 3" X .375", you should be able to tell which one by the O.D., if neither of these are right please give me the O.D. of the seal, or the part number from the PTO, hope this helps.
