I wouldn't worry about the title at this point ( ). You can't get a title with out numbers or an identity. Getting the title once you've done your homework will be easy. But you have to do your homework.

This is something that auto restoration guys really get into because it's almost as much fun digging up history as building the car (it has in my cases too).

As your car can be considered a 'derelict' car anyway, and it is on your family property, I'd drag it home and careful disassemble it and look for clues. Check for stampings, small ID plates, etc. I'd also look at the many automotive libraries scattered around the country. Two that come to mind is at the former Harrah's Collection in Reno (I can't think of the current name), and the Detroit Historical Automotive Collection at the Detroit Public Library.

While a newer car (if you can call 1964 newer), I have been able to track down the original order form for my car indicating equipment, color, trim, etc. I know the car was shipped to North Sacramento, CA. I know the build date, options and colors originally available, and the two previous owners before me. I know the car spent the majority of it's life in the L.A. area, and transported some lucky college kid to San Jose State University (sticker in the back window).

Many (not all) manufacturers have detailed records of production, and this includes defunct companies (such as Studebaker). While not turning a wrench, this can provide you with a lot of technical data to help build the car, including what it actually is.
