I got to see episode 1 and 2 tonight at a friends house.
Best not to let the made for Hollywood factor bother us too much.
Great to see the cars looking good again.

I'm thinking as far as correctness - they were just doing them close enough to get them back in 1 piece and a completed form. NOT counting the red -oxide underbellies , which was a major big foul.
They aren't concours - but they are restored.

Some quick things -
BOTH cars were built with Wire Hubcaps and Whitewall Radial Tires
They used 68 Hubcaps , Rally 2's with wrong color lugs and centers , and RWL tires that didn't come out on Pontiacs until 1970. The tire / wheel packages really rocked the boat to me.

Hardtop was built with a Hood Tach. and Wood Wheel that i didn't see.
Don't remember if i saw wheel opening moldings on Hardtop either.
Both had Rear Antenna - would have to watch again - but don't remember seeing any antennas

A little more research, parts sourcing, and massaging - they'll be ready for the big time.
