If you can find a local chandlery, maybe they will be able to help you. I will suggest taking your broken block into the store to get as close a match as you can find. Much as I try to avoid the big box of boat stores, West Marine, they do carry an assortment of blocks.

I have an older m15 that needs a new mainsheet block. The current one attaches to the step in front of the cabin (as most do) but the bearing housing has split. I epoxied it back together but it has started to split again. It still works, but it sure makes me nervous in a blow. Any suggestions for a new one? Many thanks for your collective expertise! Chris
