Halyard swivel Facnor furler SO 32

[pio]

My Halyard swivel as enormous tolerances and is not working properly anymore. Greasing does also not help. I want to replace it, but I heard that this might very expensive. I read somewhere that it would be able to repair it with standard parts with the help of a machine shop. It would even be possible to use a halyard swivel from Furlex or another brand. Also expensive, but with longer lifetime.

Does anyone have experience with one or the other solution?
