After searching for an inexpensive used GT3 console delete, I decided to just make one. It isn't shaped exactly like the OEM piece, but it does the job and I was happy with how it turned out. This is what I did if anyone is interested.
I started out with a removed center console, and I began roughing in the shape of the GT3 console in cardboard. I looked at a few pictures online and then eyeballed it to make the closest representation I could.
I decided to make my console out of sheet metal, so I got a piece of 24 gauge metal from the Home Depot Motorsports aisle, and broke out my trusty shears and rivet gun and went to work.
At this point I checked the fit and did a little fine tuning.
Happy enough with the fit, I bought a roll of generic black interior carpet from Walmart, and used some Heavy Duty 3M Spray glue. I discovered that my wife's hair pins were just the right thickness to hold the carpet against the metal while the tight edges dried.
With the glue dry, I set about installing it in the car. I ended up using some exposed local auto parts store hardware and attaching the console at the top and bottom. Maybe next time I would hide the screws, but they don't bother me too much.
I coupled this with the small plastic cover in front of the shifter that I purchased from ECS Tuning, and for a little more than $18 and a few hours of my time I have a "GT3-styled" Center Console Delete.
