I am in the process of winterizing my older RT. I had missed a couple of upshifts recently and while looking at the linkage I noticed the red spongy material that seals the heim joints on the external shift linkage is rotting away.
Online catalogs list the whole part(s) for sale for $55. I only need the red spongy seals (2). Does anyone know of a substitute part or material? The rest of the linkage is fine.
