Subscribing.... I'm thinking about going the same route. I'm pretty sure it's a block off plate for the egr and a plug for the electircal connection running to the egr that either simulates an egr or something but in either case keep it from triping the engine codes.
To complete the elimination you just need to block the EGR valve (a steel plate will do), and get a resistor plug to keep the check engine light from coming on. However the resistor plugs do not keep the computer from throwing codes, at least it doesn't keep mine from throwing codes.
The egr is one of the rare emissions systems that has several positives and few negatives.
Pros
Better fuel economy
No loss of power at WOT
Less production of NOx
Can help provide quicker warm ups, increasing engine life
If not shut off at the computer, blocking the egr could cause ignition timing problems.
Cons
Engine bay clutter
EGR wears and breaks, just like other parts on the car
It can be done. Most people have little or no problems with part throttle timing after blocking the egr. Some have reported worse fuel economy, but others reported no change.
I personally see no reason to remove the system, but if it is what you decide to do I would gladly help. It's just not for me.
i need it gone! my gt-40 doesnt have a coolant passage for it in the back and I dont have a vacuum source with enough vacuum to run the bladder in the EGR.

I would think you could run without the coolant, but the vac source could be problematic. I assume you are running a pretty wild cam, and that this is motor is used mostly for racing.
I don't believe that the plugs will keep the computer from throwing codes.
You can find them on ebay (this is the one I have). Try a search using "mustang egr"
There is a thread or 2 on this site that outlines (or references a website) how to make your own at Radio Shack. Try a search with "egr Radio Shack" and it should come up. It was within the last 3 months if I remember right.
