I believe, I have a set of 6 spare sheaves and a pair of cleat plates that might fit this unit. Lewmar
sent me the wrong ones for my size 2 unit, even though they are marked SZ2, they were too small. And they will not respond to my emails for a return.
So, the sheaves are 30mm OD with a 6mm hole for 8mm line. The cleat plates have a hole distance, between the sheave holes, of 38mm.
I paid $80 but will let then go for $40. Anyone interested?
