Ok had a minute so looked it up in WIS for you
Bolt end cover to rear axle differential, so cover to diff (torque setting indicates bolts are stretched so you should use new bolts.
Stage 1 NM 30
Stage 2 45 degrees
Bolt Heat sink to end cover 35NM

I just bought these items A2043510608 diff plate, A1713510108 rectifier , 2x N000000001536 bolts and turns out its already fitted. I really should have checked before ordering.
Too much time has elapsed for me to return them so I need to sell them.
Send me a message if you want them. I am based in the UK but can ship. Cost me £220 gbp.
^ I'd be game, but every time I plug the part numbers into FCP Euro, it says it does not fit 2013 C63
if you zoom in on my pic above you can see the 0608 part number stamped on the part on the right side and the 0108 part number on the box for the part on the left, and the number on the bolt packaging. All fit perfectly on my 2015 c63 w204. The parts are not made for USA c63, but they fit, as mentioned above they came on Euro and Australian c63 w204s. Just buy the guys parts and install them.

So you got the rear Ultra subframe brace to fit, that’s excellent. Did you have to grind out the bushing holder, or did they modify the design after I told them they don’t fit I wonder…
I was going to try to fit mine this week, but think my new diff pump is now in the way.

For some odd reason, MBUSA stopped opting the rectifier for the FL C63, except the BS. It could be the reason why it says it doesn’t fit. Rest assured, it fits on my 2014 sedan.

maybe you can spot if it was changed

How bad is the rear diff to drop and do this upgrade if I have access to a lift? I see the WIS instructions, but for an average home mechanic with lift access.
