Royce, have you considered running without the top? My buddy used to drag race his Cobra kit car, which ran low 10s with a 460 Ford and C6, and he had a windshield, no top, and he had wrist restraints which attached to the latch of his 5 point SFI safety harness. He built a funny car style cage, and at one race, the car turned right during a wheelstand, climbed over the concrete guard wall, flipped over, and landed on the grass on the other side of the wall, an he walked out with no injuries. The wrist restrains are to prevent your arms from getting outside the confines of the car body, and it worked quite well in his case.
