I'm not sure I've seen a GT40 intake with a egr spacer on it permanently. But then again, I haven't seen big foot, that doesn't mean it doesn't exist. Do you have any pics?
What I think your talking about is the "internal" EGR passages v. "external" EGR.
IF your going to use an elbow (it will block the internal passages) the elbow mounts the EGR hardware and dumps it into the intake tract. This is how the 94-95 mustangs work. You can use an internal EGR passage or non-internall passage intake with the eblow and stock EGR sytem (that unless the whole EGR system is broken keep it).
Now if your going with a fox style intake, t-body swap, and EGR setup they are internal EGR passage setups. IF your dumping the EGR then you can just block the internal EGR passages.
Basicly the elbow is our (94-95) egr passage, were the others have it cast into the intake.
Also note that the lower intake will also have to be an internal passage EGR intake. You can tell if it is if the lower has a round/cirlce hole in the middle of the lower intake, there is a hole in the gasket (all stock/factory/EGR gaskets have this hole if you want to see its location) at this point.
It will fit *if* you swap over the the fox tb set up. Because of the built in egr the snout is longer and adding the elbow will make it even longer. Making the throttle cable/cruise controll cable etc. not long enough. So you would have to get real creative to make it work. Now all aftermarket intake are designed for a fox BUT they don't have the egr built in, so adding the elbow is no problem and will bolt right up.

Darn right, I did it and would never want to go back to the SN95 setup. It was more involved than a standard intake swap, but the fox setup is much easier to work with IMO.
