Dad's 69 'Cuda Fastback...Where in the world is it?

I thought it would be easy once I found the VIN number. not so, though. The VIN number is pre 1981, when VIN numbers were standardized to 17 digits. the VIN number for the Cuda is 13 digits. Carfax calls it an "invalid" number. I was able to decode the VIN on www.decodethis.com, so it is a valid number.

I paid the $30 at www.government-records.com and came up empty.

Still working on it.
