New to Site and have ? about Bill Thomas cars

[69Chevelle L78Deluxe300]

I am impressed. Two days ago I didn't think I would find any information on the Bill Thomas Cars sticker, and now people on this site actually remember seeing this car from a couple of years ago! I did buy it from Steve two years ago when he was still living in Phoenix. The car was never licensed since the original owner, so the title had never been turned in to the state. All 3 previous owners names were on it with their signatures and the mileage notarized. This allowed me to register it in AZ with a "box A" title for original mileage. I got the original block with the car and it needed a complete rebuild. The body, interior, weather stripping, etc. are all close to new condition. The only parts of the car that were a mess were the engine compartment (someone had sprayed everything gloss black) and the underside (someone had sprayed black goop). I refinished the engine compartment while the engine was out, and I had the underside blasted with baking soda (yes, Arm and Hammer) to remove all the black goop. This soda blasting is a miracle for removing this stuff without damaging anything else! I fired it up and drove it for the first time last week. Even better than I remember from back in the day when I graduated from high school in 69!
I guess the Bill Thomas sticker must have been just an advertisement.
