Okey Dokey here goes a few observations before work:
The '69 Chevelle could've had a tire change at the dealership before it ever left the dealership. We used to do it all the time. The finance manager would upsell tires and compare them to "builder grade" carpet. The take-offs would then be sold (or stolen) to employees, etc. As a kid, my cars ALWAYS had brand new take-offs and I went through them quickly. Heck, a teenage gearhead with an unlimited supply of free tires? What could be better?
The "Charlie Jacobs" Chevelle has been substantially modified as it looks to be a leaf spring rear suspension with an altered wheelbase.
The "Tire Town Rat" (I'm darn near positive, unless there were two) is the Yellow ZL-1 that was found and owned by Bill Porterfield. If my memory is working, that was a double COPO from Berger, and the #3 ZL-1.
