I had a THS2727A. I'm not sure if the belt was the same as yours, but I was also unable to locate a replacement after mine crumbled. I eventually gave up, and added a v-belt pulley and an external motor (an expensive option). Now I have a rockwell table saw that has a similar cogged belt, but I believe it is shorter. However you might check a Delta parts dealer and see if they have any the same size as yours. The last time I tried to find one was 5 or more years ago. Good luck.
