You're right 'Oldfart', the driver looks incredibly vulnerable! Although we are building our car 'as-originally-raced' it still has to have a motorsport approved cage, so we will add a diagonal bar with padded support behind the driver's head - and hope I don't get from behind by a bloody great muscle car!! We won't fit a high-back seat in a car like this.
Yes, being able to communicate directly with Jerry Entin (we've exchanged several e-mails) is a real privilage. Only a handful of drivers raced the Cheetah, and I've been luck enough to correspond with two of them.
