This may not help much since I drive a Contemporary, but it may give you some perspective. I am also 6'5" and around 280. I had to remove the drivers seat and sit directly on the floor, this brought me down and back the several inches I needed to fit into my car. I am working on a fiberglass comp seat that will have no padding and bolt directly to the floor. I look "through" the windshield, but with the top off, the top of my head does go above the top of the windshield. If it helps, my waistline is at or above the windshield on most of these cars. Mark
