That kit is about physically removing the valve from the engine and using block off plates to cover the remaining openings. You can just pull the lines from the black box. Plug off the egr nipple, the two thermo nipples just above the t'stat. Follow the two other lines to where they intersect with a two, three or four way connector, distributor in MB speak, and replace those with a one fewer connector. You'll have new connectors and your exhaust will no longer pollute your manifold.

what is the benefit, other than not polluting my manifold? Performance?

Having a non-functioning EGR or blocked EGR will help in not having the manifold clogged up with carbon, along with possibly better performance.

Your performance won't deteriorate any more than it has by trying to use hot exhaust gases instead of clean, more dense colder air.
Cold clean atmosphere has more power than carbon monoxide ladened gas.

I appreciate the explanation without removing the egr. But I am a dummy!! I need pics to go with what your saying.

I second that. I want to do the same thing on my '85 300sd Cali. I'm much more visual, pics would be great

Okay,
Pic 1 the egr valve and the thermo nipples have a rubber plug on them.
Pic 2 the distributor that comes up from the vcv and into a green damper used to be a four way, new three way now.
Pic 3 Brian's kit.
Pic 4 the line between the bottom of the vcv and the black vent line used to be a three way, now a piece of rubber hose, or a two way.
Pic 2 & 4 had lines coming from the black box.
A line from the egr valve used to go to one of the thermo valve nipples, then from the other one to the black box on the top row of three. One lie each from the top three went to above explained orifices.
And the last pic is of the 3/2 valve and black box that used to be on that car, the view is of the bottom, note the two lower nipples are not connected to anything.
SO, inspect what you have, take before pics, I did not, and start plugging and removing.

Good point matthew, the 85's are different.

Goodness your cali models are so much more confusing then my federal! I guess I should be blessed to know that I only have to deal with the ARV and EGR.
