I had to order 25 o-rings to get 1 for my new to me oil cooler adapter so I have 20 o-rings I can spare if any of you need one.
If Toyota had my o-ring, it would have cost ten bucks so I went to Grainger and bought 25 and I will give the extra away FREE Plus Priority shipping to mainland U.S. members.
I'm not shipping over the us border for any amount of money, it is a PITA.
