904 Tailshaft Bushing

I have a slant six 904 combination in my Scamp. Is there an aftermarket tailshaft bushing that is sized correctly on the inside dimension?

lit seems that the only aftermarket bushings available are aluminum,and those seem to have an inside diameter that is too large to support the yoke. The yoke has no appreciable wear in the area where it contacts the bushing.

Does anyone know of a babbit/copper bushing that is sized correctly ?
