Cal,
Bad news. I've done some preliminary ergonomic calculations and have determined that, at your newfound height, or more correctly lack thereof, you will no longer be able to see over the steering wheel. I would offer you the GT40 back at a most reasonable price, but morally I cannot allow myself to do so as you would present a danger to yourself and others if you tried to drive it without being able to see where you were going.
Sorry. As a consolation I can offer you some Florida wetland, or a vintage bridge in New York, also at eminently reasonable prices...
