Bonneville Landspeed Racing - Let's Try a Thing.

What work is done to the tail panel to create a Daytona? Or is it just the wing and the back glass?
It is just the back window, the wing and in trunk braces from fender top to chassis. Back window is done. Have spoke to Grant Janak in length about Bonneville requirements. He is on board. Big issue I would like try to make the nose myself to save money and have a few subtle changes. So, would need to order the wing as i havent sourced a place for tapered air foil in extruded aluminum. And if I calculated wrong, something breaks at speed, it could be disasterous.
