I have searched everywhere and can't find anything on this issue... including in my conversations with Pelican parts where I bought new Bilstein shocks for my '76 914 rear end. So please excuse the redundancy if this has already been addressed.
The old shocks were the original Boge. When I removed the top spring shock plate, there was an orange rubber donut that is apparently some sort of shock pad that sits under the shock plate and slides down to a shoulder on the threaded end of the shock shaft. See photos. One side - shown in the photo - was still intact, but the other side had completely disintegrated, leaving only the steel washer that was originally vulcanized into the orange rubber donut. No one seems to know the name or part number for this part, or if it is even necessary when replacing the Boge (seems to be a Boge only part?) with Bilstien shocks. Does anyone know what to use in lieu of this part if you can't replace it, or isn't necessary with the Bilstein replacement?
Thanks for your help!!
