Have two belts for an S-chassis sled (670 Summit, 583 MXZ, etc). Came with the sled, I dropped and rolled it when I first bought it and have never used them since the clutch center to center was different. Cleaning out the basement, figured someone could use them instead of throwing them out. One belt was slightly used (still looks really good) other one is brand new. PM me your address and sled and if they are going to fit, I'll send them off early next week. If you are in Calgary area, I can drop off somewhere or you can come get them. Sorry, first come, first serve.
