Jay Kline Chevrolet (Twin Cities) was the sponsor of these vehicles, many hi-performance Chevrolets/Corvettes came from this dealership. I had a '65 Corvette that was ordered out of Jay Kline Chevrolet. They used a made up chassis, I think Buick control arms. They were back yard hot rod cars but they ran.
The Vintage Motorsport book, "Specials" goes into detail about these and other hot rod road racers.
