Hall Pantera engine compartment roll bar

Are the chassis type components just for demonstration purposes of the roll hoop or part of a kit that you have to reinforce the inner rockers?

On purple passion, maybe that was how Gary got the additional rigidity to compensate for the Targa roof.

Julian you've surmised everything correctly. The chassis stiffener was developed for purple passion. That entire "purple" assembly as seen in the picture is intended to be fitted into the car. The rectangular sections with the holes in them must be fitted within the rockers, as you can imagine that requires some major hacking on the chassis.

There were other pictures hall had of this system.
This must be the mock up because he had another where the roll bar bolted on and the rocker tubes were individual and slipped in the rockers after opening the ends in the rear wheel wells.

Then the rocker tube bolted with a flange to the front inner wheel housing.

Those pictures he gave me but I have no idea what I did with them.

Apparently the Byers Bros were the fabricators and when I ask Bob about making me a roll bar for the engine compartment his exact comment was "NO FREAKIN' WAY!" LOL!

When I made my roll bar, I tried to see if I could get it into the engine side of the firewall. I could not do it unless I started with a 2-piece roll bar or cut the body. Either way it would have been a permanent piece when the car was done but I wanted it removable.

I think Hall's goal was to achieve rigidity for the roof cut, whereas I would expect most who install a roll cage are looking for a sanctioning body approval for racing. At least I would hope so as a roll cage in a street car puts the tubing in too close proximity to occupants heads with dire consequences in an accident.

This is the assembly that I mentioned in the discussion of the factory T top car and Halls replica.

Gary told me that even with this assembly in the car it still flexed so bad that he couldn't get the roof panels to seal and that the entire car squeaked from movement.
