Mercedes Benz repair: Drive Shaft, mercedes benz 300se, universal joints

Question
I have a 1989 300SE and need to replace the universal joints.  When I look up the parts I get what they call a C.V Joint and wonder if this is the universal joint.  If so what else should I purchase as they offer bushings for the drive shaft and a couple of other items.
I appreciate your help.
