Ok, I found exact replacements at Rig-Rite, not cheap but they are 33% heavier than the originals (I weighed the old and new).
NG1-3 (50 mm) $22/each and NG1-4 (60 mm)$32/each.

Not cheap, but do you really want to unstep the mast or climb the mast to fix a sub-par sheave solution?

Around 1985-1986, Hunter was switching from Kenyon Isomat to Z Spar. See if there is a sticker or anything stamped into the base of the mast that can identify what you have. If not post some photos of mast and boom so we can help to identify. If Z Spar you can go thru US Spars or this forum store. If Kenyon Isomat go thru Rig Rite

Hopes this helps.
