Andrew, you're welcome to stop by anytime. GT40NZ was bought up by someone in the mid-west and ran into the ground. Not sure how many cars they made. It's basically a KVA/GTD space frame knockoff. There are about 7 40's here on this side of the cascades. Always happy to talk cars.
Better yet, stop by Doug's next time out. He has some real forward thinking body work ideas including a pre-top coat greasing of brat juice to improve paint adhesion!
