We are talking about a 1982 300D with a manual transmission. It is not a USA spec car the manual is original.

Where my driveshaft connects to my transmission there is a coupler? that looks like a balancer and it has cracks in the rubber. What do I buy to replace this part? At the rear of the driveshaft I have a flex disk like a car with an automatice transmission. The one on the front is different.

Can you post a picture......

A picture is worth a thousand words.....

And I know lots of guys are going to want to see what it looks like too.

I will post a picture eventually but I have to put the car up on ramps to get to it.

If you have access to the shop manual it calls this a vibration damper(section 41 in mine). It makes no mention of replacement that I have seen. I am afraid this may be part of the driveshaft.

My Manual is at home so can not look till tonight......I didn't know there was a difference on the flex disks. Obviously this is a good thing for those of us considering a future manual swap where we don't have an entire parts car handy to know.
