Great looking dash, much better than my '63. Not to detract, but...aside from optional seat belts, the only impact protection in a 63 was the padded dash.
(Short background: I was among other things a USAF Flight Surgeon and trained accident investigator. We all took the formal course in Human Impact Tolerance. Since then i have been very conscious of potential secondary impacts in the cockpit. For example, I once evaluated a NASA test pilot who had ejected from a Hornet. His neck flexed so far that his mandible was fractured by the oxygen regulator, on the right chest strap. That Martin Baker ejection seat was engineered to modulate the acceleration up the rails, to a much lower "jolt" than previous. So...)
Even with seat belts on, a significant frontal impact would result in: driver's head against rigid steering wheel, and passenger's head contacting the (padded) dash. Conversely, a tight shoulder belt - tight!! - would almost certainly protect both. Thanks for listening. I promise pictures of shoulder belts in my 63 soon.
