I would be very interested in seeing the test data they have to support their 2 year use requirement. As with most things that need servicing or replacing typically they are subjected to varying types of testing to determine their service life. I've long believed that for a door car the certs. should last 5 years, the open cockpit cars allow UV, and weather in general to effect the belts. Don't want to upset the guys with open cars just stating my beliefs. Joe
