Since there is not a kit made up to fit a Mercedes, I think a good machine shop would easily cut and weld and fit that simple in and out clutch into your front or rear driveshaft. I had one on my Ford Ranger a number of years ago and it mounted near the rear "U" joint. They have only two positions to go into "lock up" and they are 180 degree apart. Even on the Ford, if I would lock it up in the wrong position, you could tell it from the vibs as soon as you reach 60/65 mph. And maybe on the Benz you would loose that fine driveline smoothness with it mounted. But if you keep the factory balance and then add the clutch, you probably wouldn't loose much.
