Methanol and E85 O-Rings

I am happy with the o-rings after the first race. I would love to have some extra rings on hand but they seem to be pretty pricey to be replacing every race. I would be willing to put your logo or decal on the race car if you could provide a few more to have as back up rings when needed. I would be happy to send you pics of my midget/sprint car and schedule for the USAC season.

super thanks
