It is indeed the Revell GTi. I had intentions of following you with the widebody Rieger (i think that's how it's spelled) kit. But today when I picked up the GTi and some styrene sheet, they were out of tamiya expoy putty. So, I used the goofy, but still cool aero parts. I needed to use the flairs because of the wheels I'm using.
Where you planning to use your hood scoop thing? I'm probably going to have to make a new one for the hood to clear my air cleaners for the dual carb 283.
