I need to replace the 4 aluminum mast sheaves on my Dufour 31. They're so worn I'm surprised they even spin. Each measures 55mm x 15mm x 13mm as best as I can measure. Can't find anything close to that or even a single source with a good selection to choose from via Google. Mauri Pro Sailing are the only site that shows any kind of selection. But nothing close.
Any ideas of where to look or who to call would be very appreciated.
Are the sheaves themselves worn? By that I mean the outer grooves where the halyards run.

If it is only the axle holes that are worn, they can be drilled oversize and bushed with bronze or S/S.
