there is a silver blue one a past co-worker of mine has since he was young (I still run into him). He does not advertise he has it. Its a 440 with black interior and top. Just sits in his garage. Add that to your list. I always tried to get the car from him, gave up. Its been so long, I cant remember if its a 4spd or auto, think its an auto. Non original motor, from what I remember. I can find out if you want me too.

Here is another one (a 4spd, been here a while)
