Good news! Looks like I might have some belts soon! I bought a XXX-S to try some out because I had a hunch and it's looking very good. I anticipate having them within the month. Just thought I'd update! BTW... all XXXS cars have a tensioner, right? Or, is that just the longer belt? The one I have has a tensioner... that's the one I'm working with. I can cast and make pulleys and tensioners but that's going to cost extra.
