I have one too, and I used to have a picture of it, but I can't seem to find it.
Anyway, it is off of a 98 SVT or any pre-98 Contour/Mystique. It is correct the access doors have been discontinued. Install is easy, it just snaps into place, and hides all the wires and such on the back of the trunk lid.
Call Bill Jenkins, he will know what you are talking about and be able to get you the part at a discount, tell him you are part of the CEG.
