Finding out if its a GT or GTA (automatic) is essential-and easy. Go here:

and order the production report for the car. $17 basic will tell you what you need to know, others look prettier and will give statistics that will get you all jazzed up about its rarity.
It could be a GT/GTA with the A-code 289. They had to have 4bbl V8's, so the fifth digit would have to be A (289/225hp), K (289/271hp), or S (390/320hp). Advertise it well on the web, lots of overseas interest in these cars. My friend just sent a '67 GTA S-code ragtop to Finland a couple weeks ago.
I'd be interested too if you weren't on the other side of the damn country.....
