I have. The one thing they all have in common is that they have rear-facing stringers off the main hoop. Over on the NASA site a Miata guy was saying he wasn’t allowed to run an HPDE in Arizona with one of the Hard Dog bars that is mentioned by name in the CCR, because his roll bar didn’t have a diagonal brace, and his rear stringers intersected the main hoop further than 6 inches (I think) down. Essentially they were enforcing competition roll-cage rules for HPDE. Maybe they guy was a jerk..who knows. Maybe I should look into SVRA...does SVRA host HPDE’s?

I actually did look into that. The competition car doesn’t have a separate roll-cage, it’s integral to the car’s structure (as required by NASA rules for the class on which it was based). Factory Five DID say I could fit the 289 body on the Challenge Car chassis, but they said they “would not support it”. Still waiting for clarification on exactly what that means, but, at the end of the day, the Challenge Car doesn’t look like a classic Cobra to me. I think I could probably figure out something like what’s in your car and keep it removable if I play my cards right. I’m pretty handy with a TIG torch and a tubing bender...
Thanks again for the ideas, Jim. I’ve got to check out Morris’ car.
