I posted pics of the Driveshaft Piston people have talked about and a picture of the bushing I received from Gordon Criag of South Africa that is supposed to reduce/eleminate the clanging noises eminating from driveshafts as they age.  

Pictures are posted in two locations, the Syncrolist (syncro.org) group under the driveshafts folder and the Syncro group under the driveshafts folder.

I have yet to install it, but I'll report when I do.
