Update:
The suspension rebuild is for the most part complete. Near everything was replaced: H&Rs, front bistein sports, (firm) front sportline control arms, sportline subframe bushings, 500e front and rear sway bars, adjustable camber arms, rear wheel bearings, diff bushings, and a lot of undercoating was applied. The rear links were all replaced last year.
There is not a lot of clearance in the front with 225/45/17s on there. I am using the biggest bump pads and need to install the fender spacers to get a bit more extra room. We have been fiddling with the rear ride height and have it pretty close to where it needs to be.
I had a shop do a sportline alignment as well. The car handles very nicely and the floaty-ness is long gone.
The big news is that I managed to find a 86 300e 5 speed at the local junkyard. I picked up the transmission and all necessary swap parts today. Sometime next year, I will convert the wagon to a 5 speed manual. The combo of the 3.6 motor and the 5 speed will be killer. The automatic in the car is shifting badly and flaring bad between the 2/3 shift. There was a receipt for work done to the transmission when I bought the car, but the previous owner must have just had only reverse fixed.
This fall, I was able to find a late style valve cover off a c280 so that I can use the 3.6 crossover tube. Seeing I am using the w124 wiring harness, it is much easier to use the original valve cover as the channels inside fit all the wiring. We are going to dremmel the later style channels off so that it can fit the existing wiring. I am curious to see what if any difference there will be running the 3.6 tube.
