No prob!

They have a kit on mercedes source that comes with 4 diaphragms, instructions and I think some sort of grease for under $45. I only need 2 so I just bought the individual ones. I'm not sure if the grease is real important I'm just a DIY guy and this mercedes is the first car I ever worked on or even wanted to work on. I used to just take my other cars to the pros, but now I can screw up my mercedes all by myself! I will say Msource shipped fast and they put a pair of gloves ini the box and a lemon head candy, which my great dane promptly ate without permission...BAD DOG!
