We have letters to/from Yenko Chevrolet & the NHRA, and it was VIN#, selling dealer, and original owner's name/address...the last part got fudged some, 'cause there are several salesmen's names, dealership owner's wives, etc...if the car wasn't sold but was in the pipeline, then they put down whomever came to mind!
This worked for the '69 cars, but for some reason NHRA never let the Deuces in...even today they're left out in the cold...
