trac 14 traveler sheave size

My Trac14 main sheet traveler sheaves are falling apart. I can measure outer/inner sizes but not sure of exact language in catalogs. I guess 3/8"ID and 1 1/8" OD. Anybody ever replaced these? What size do I order? P/N's maybe. TIA
Maybe some photos would help us help you.

Here is your photo. Are there any marks on names on the car?

No names or marks that I can find.
