I did not have any gear shifter bushings on my recently acquired 1986 190D with an automatic trans.
I picked up two today and was able to get the back bushing in. I boiled it in water to slightly soften it and used a spray silicone.

The front bushing...that is another story.
I can't see how it is possible to replace that bushing while the arm (I think the arm has 2 or 3 holes, the rod goes through the top hole) is sill attached to the car. I am trying to remove the arm but can not see how it is possible without cutting a hole in the floor

I removed the electrical connection going to the shifter underneath the car to buy me some more room.

The problem is, I can't even see how the arm is attached. I see what appears to be one hex type screw.

Does anyone know how that arm is attached and any pointers on how to get to it?

I could only find posts concerning this about other Mercedes models that look like there is a little more room up there to work.

Thanks, I am stuck!
