....switch the drive flange from the four bolt to the Crossfire 3 bolt to hook up the drive shat? YUP! But to adjust the new screw after remove the drive flange you need a special tourque meter, is require to set up the tapered roller bearing in the diff.
Do you know if the C55 or CLK55 has a posi rear end? What is that?

Thank for the very good information! A posi is a differential that supplies power to both rear wheels when accelerating. My personal favorite is the Quaife/Torsen type because they can shift power to the wheel that has the most traction.
