I've tried and tried and can't seem to get this belt on. I'm trying the belt they sent with the s-trim kit, but as far as I can tell it's just a hair too short. It is only about 40 degrees outside and I figure that maybe if I tried to heat it up with a blow dryer or something that would give me that extra little bit, but I don't want my tensioner maxed out either. What should I do?
