Is that a group track day? I only live about 40 minutes from Pocono. They finally put in a real road course instead of the potholed mess they had for so many years.
I've been trying to do what you suggested but it's tough to track anything down. If I don't find something by May I will make sure I get out to the Carlisle show in May. I didn't know about that show last year or I would have gone already. In the later 70's I built a Bradley GTII for myself which had a rep for being too tight for tall guys. I ended up fitting in it just fine with very few mods.
It did get sold last fall, now the new owner is selling it. It was owned before by a guy named Robin that was a member in here that had moved to Canada, eh.
