The track is Lewmar Size 1. It would appear that Bill used:
1 x Size 1 End Stop With Single CL Sheave (Lewmar Part # 29471031BK): https://www.lewmar.com/node/13230?v=26088
1 x Size 1 End Stop With Double CL Sheaves (Lewmar Part # 29471032BK): https://www.lewmar.com/node/13230?v=26089
I am sure Bill will eventually see this post and confirm or correct or you can contact him via email directly at GreatKetch "at" yahoo.com.
