I think that same X-1/9 driver when they were forced to run WITHOUT the top on, attached it, and painted

REAR MIRROR on it.

Tech / Stewards weren't amused

I also had to do the same thing on my Wabbit. I just got a longer top "bar" and mounted it with some springs so it will slide in and out of the existing attaching "tabs"

I left the bottom seat belt type fastener attached, so now it releases from both top and bottom.

I really think this is a stupid rule, since if your upside down, don't you want to get out as fast as possible, and now that it's attached at the bottom, you've just reversed the entire problem.

Oh well.
