Replacing the belts on my '86 PCM 351. Belts from skidim are $18 and change plus $12 shipping so, call it $30 for new belts. Trying to find them local and all the part numbers carry over to V-belts with teeth on them which I cannot use. What are you guys using for belts or what are the dimensions of the belt so I can try and save some money by finding them local and not having to pay shipping?
