Hi everyone hope all is well with you all.

I need to replace my rear flex joint in my 1978 240D 4spd and I want to change the transmission mount while doing this job. My VIN is 12312310084647 and I am having a problem finding the correct mount.

Any help would be greatly appreciated.

Also if anyone has done this job, does the entire driveshaft need to be removed to just replace the rear joint?
