Those would be the RH bushing from a TR2-4, I believe, P/N 36998. I agree,
a worthwhile upgrade. I also like to add grease zerks so the bushings can
be lubed if the shaft doesn't already have them. Don't know about a TR6,
but the Stag doesn't have enough room for the TR3-style zerks on the shaft,
so I put them in the housing instead.
Also a good time to replace the pilot bearing; and make sure the "dowel
bolts" are present.
