I have a Craftsman miter saw that is 25 or 30 years old. It needs a new belt. The only number I can find on the saw is 3532375. The belt is 7 1/2 inches long (diameter before it broke) and 7/8 of an inch wide. ***** can not find the number in their system. May be too old. Any ideas on how to get a belt to replace the broken one? Thanks.
