Does any know if there is a soft rubber seal between the yoke and the rear driveshaft coupling on a late style rear Alfetta driveshaft coupling, i.e. it would slide over the tip coming out of the yoke that engages into the driveshaft coupling and then get compressed as the bolts holding the rear driveshaft coupling to the yoke are tightened? This is on a Milano race car running Alfetta parts, but I don't have an Alfetta manual. The Milano rear driveshaft setup has it, and I suspect the Alfetta does as well. An Alfetta parts manual or a Haynes workshop manual will likely show it, or anyone familiar with late style Alfettas will know.
