I just called Jet and talked to the guy in the Technical Dept. who refused to help with the Woodcraft belt and he sent me on to the parts department. Try 1 800 274 6848. Maker sure you get a real 3M belt.
They were outside Nashville I believe. Tennessee for sure. The delivery to me in VA was about $8 and took about four days. Not worth much of a drive to save that.
There is a video on YouTube that shows them reinstalling the belt. The whole video is 57 seconds. Obviously some time lapse involved, but not a lot. They just put the belt on and it ran. I was scoffing. I got mine and put it on in less than ten minutes and it ran. After all the BS I have been through I was hugely impressed. The video wasn't THAT far off.
