Hi- I have a 1969 Chrysler 3.5 hp air cooled engine that is like the West Bend Style. Model # 313 and serial 107*. I am looking for part numbers for the driveshaft seals (I believe they are identical placed back to back ) and also the prop shaft seal. OR if anyone knows where I can purchase new seals. I do not see any numbers stamped into the seals. Thanks, Gary
