Here's a VERY RELEVANT Thunderbolt story for you:
In 1972 my grandpa was car shopping. He was working as the Chief of Construction on the NORAD project in Colorado Springs. At the time he had always driven Corvair's and actually had a little side business on the weekends tuning the Corvair multi-carb setups for people. He went looking around and found for sale a '69 454 Chevelle, a '67 390 Mustang, and a '64 Thunderbolt. I don't even know why the Thunderbolt was in consideration for a daily driver, but it was. After considering all 3, the Mustang was chosen (and we still have it today). My grandpa said something was wrong with the Thunderbolt engine, maybe needed a valve job or something, and he didn't want to buy a car that needed work. And then 3 months later him, my dad, and my uncle pulled the engine out of the mustang and completely rebuilt it...
My dad always tells this story and does a face-palm. That they could have owned the Thunderbolt and they ended up ripping the engine out of the Mustang anyways.
Looks to me like the car my Grandpa was looking at is the same car that you just posted the sales receipt for!! I saved this. Small world.
Edit: I called my Grandpa to ask him about this. He said there were 2 or 3 Thunderbolts running around Colorado Springs at the time. The one he looked at was a 4 speed. He said he wasn't all that serious about buying the Thunderbolt even though my Dad and Uncle were clamoring for it.
