I recently acquired the spare set of keys to a 1969 Ford Mustang. It was my uncle’s who passed before I was born. The tag with the keys had a partial serial number and not much else. Where can I go to try and find the full vin and possibly locate the mustang?

Ok yeah I will keep on trying every avenue I can to find this mustang. My family is still trying to get me any info they can find on this 69’ mustang that may help me. Thanks!
