yes sir ken there were two different styles my 58 has the o ring just replaced it last week
 
The earlier pumps had the seals. If you have a NAPA in your area their number is 5068. IH part number is 35507420R91. Most any auto parts store should be able to cross it over. The new seal will be considerably thinner than the old one, which will allow you to seat it where it does NOT ride in the groove the old one created.
 
thanks john I went to find that number and then got side tracked lol are you the one who tried those viton o rings ?
