ANSWER: I am not sure about belt drive. I used it on a chain drive and it was piece for piece replacement. I would look at your existing drive/parts and compare with pictures of what they offer. My neighbour did it that way and located a right kit. Also, if you have the original opener manual it lists parts and part numbers I was lucky to have found mine, Good luck. by Pawel P a
