Thank you guys
Amel have replied and confirmed that spare parts do not exist for early furler models.

I will look for a machine shop here in Italy that can do such part.

My other problem becomes now removing the furler  from the forestay without the full mast falling down.

Can I just loose the backsty and then completely unscrew the forestay to slide off the furler?
Or do I need a crane to do that?

Any suggestions/tips are super appreciated

Thank you!
Riccardo
