Needed:
E55 rear subframe, E55 axles, E55 driveshaft, 4 bolt transmission flange 2402720345, nut 1409901150, C219 CLS63 LSD (has same ratio as E500) You can reuse the E500 rotors and calipers.
A 12 point deep socket is also needed to replace the transmission flange. Cannot remember the size.
I replaced my subframe mounts at the time. The tool was pretty expensive

Unfortunately, the car was T-boned at the front A-pillar (took a 45-50mph hit) Car is very safe. The 2018 Accord that hit me looked much worse.
Not sure where the car is now. I bought it from Copart with a clean title for around a grand. It needed an SBC pump (warrantied by MB) and some maintenance, ended up back at Copart a few years later. I sometimes wonder who bought the car as it had some great parts. What a great safe reliable car.
