Dave - There is a book titled "In Search of Mustangs" that I have not been able to find. It is out of print, but is supposed to have some way to reference previous owners. Maybe someone here has a copy and can help you. I've been trying to find my first K code convertible for a long time and could use similar help.
The book is actually called MUSTANG PRODUCTION GUIDE, and is subtitled: The "In Search of Mustangs" Registry & Census. Volume 1, 1964 1/2-66, was printed in 1994, and is currently out of print. Good luck finding a copy. It contains hundreds of pages of VIN's printed in small type, with four columns per page! Each column contains 60 VIN's, for a total of 240 cars per page. There is also a smaller section called VIN-Plus. VIN-Plus refers to complete (or mostly complete) warranty plate data, and each page has only one column of numbers with 60 cars per page. Many include the owner's name and location by state or country. Some are noted with comments such as "GT", "NLO", and "DOOR". "GT" means the car is claimed to be a GT. "NLO" means the car no longer operates, and is probably scrapped or wrecked. "DOOR" means this is just a driver's door from which the warranty plate information was taken, with the status of the rest of the vehicle unknown.
All of the data is sorted by year, assembly plant, and build sequence number. Of course, there are many K codes listed, but they are few and far between when listed with all other Mustangs! This is to be expected. It's interesting to see that of all Mustangs found in this registry, "C" code Mustangs account for almost 50% of the cars listed, with "T" code cars between 30-40%, "A" codes between 10-15%, and "K" codes are between 1.5-2.5%.
There is no way to know for sure if the infomation in the book is completely accurate. If you know the VIN of your "first K code convertible", send me an email, and I can look it up to see if it is listed in the book.
