Where can you buy plastic sheaves for a 321?

Anyone know where you can buy plastic (delrin) sheaves for spinnaker and topping lift on a B321?

These are 17 mm in diameter with a 10 mm hole.
Width is 15 mm.

After taking the mast down, it was clear these are pretty worn after 14 years of use.

Tried a number of places. Next stop for me is Charleston Spar...

Charleston spars is where I'd start.

Rig-Rite can sell you the sheaves you need although a wiser choice might be the aluminum sheaves available through Garhaurer. In either case, Google's your friend.

I have seen many sheaves in my life, but never such a small ones (10mm axle with 17mm OD). Are you certain the dimensions are correct? OD in particular.

Yes, indeed. Took them out myself.
One from the top of the spinnaker halyard was worn to the pin since it must have got jammed. There were two at the same location so I just switched them, but thought I should also get a replacement ready.
