It has a tube frame, but has aluminum sheeting over the frame to appear like the monocoque. It started life as a KVA, but I had extensive modifications done to the body to correct all of the inconsistencies of the KVA, to make as accurate to original as possible. Aluminum head 347 stroker, reinforced 5sp Audi Trans with taller ratio, electric water pump, proper smiths gauges, ceramic coated bundle of snakes exhaust, proper Lemans style grills, and also have the street louvered grills, etc. the floor/firewall is bare aluminum. I will text more pics shortly.
