Just tell them they are on order, took me 4 months to get my last set, I sent to get redone.; Went to three tracks this summer and they all let it slide, everybody is having trouble getting belts. and there is no way they wear out in a couple months anyway. NHRA says the sun rots the material, heck, I bet my belts don't see the sun more than a week in two years. It sits in the trailer. Hell every circle track car in the country uses out of date drag racing belts. They wreck cars many more times than drag racers.
