Wisconsin ads are likely the Yenko 427 Nova from the 11/69 Hult Chevrolet ad below?
Being Ohio, there may be more of a chance the subject 427 Nova is the Yenko in the 07/72 ad posted previously also here again further below w/ another Cinncinati ad from 04/73 which is likely the same car but different phone #'s/owners?
What seems questionable w/ the cars in most of these ads is how they all sound too complete to be the OP's Dad's car, even if subsequent owners recognized/knew what it was after Yenko added L72/Stripes/Badging removed?
Great thread also good to hear word about this car is spreading!
