New ones are $75, so I removed it and wrapped with steel wire and a hose clamp, which worked fine for years. I got a replacement at the junkyard a month ago.
A few other things I am just learning. To stop engine shaking at idle, adjust the "rack damper" bolt at the rear of the injection pump (search posts). Your 85 should already have the longer bolt, so should be able to screw it in more, after loosening the lock nut. Often the air cleaner bracket is cracked from shaking. You can get new ones now for $16. Used to be >$100. You can simplify your vacuum system by eliminating the EGR controls. Your EGR valve may no longer work anyway.

Tram said not to mess with ANY adjustment as then the kick-down switch will not operate. What I might do is find how much slop is actually needed by going to the full throttle stop and then seeing when the kick-down switch engages.
Here is a video I did for him:

The only correction I would say is instead of spacer at the ark, instead put behind the clip by the firewall.
The firewall bushing is fine. It is the bushings in the linkage I need. I did a search in several places and doesn't bring up anything. I will ask the Classic Center once I have the bread to join the Mercedes Club of America.
The slop is about a quarter pedal and be happy if all I could reduce it to is 3/16 if that is what it had to be. I just want it the tightest possible.
I also want to make only one trip to the F.L.A.P.S., so going to pull the trim first in case I need something else.
Tram did go through EVERYTHING so doubt I need to do it for a bit. He also does not want me to touch the smog equipment, but what good is it when it only causes reliability issues? So the E.G.R. will be eliminated and vacuum going to the, the name escapes me, the thing that limits the boost and can cause the wine I am experiencing. Plus, think I am going to test and adjust if needed the turbo and maybe shimming the A.L.D.A. for more power, which means to a point better fuel economy.
