Not to sound like an a$$ but did you inspect this car before shelling out that kinda money for what is going to be a parts car? I've bought quite a few of these and with pics alone can tell if they are salvageable.
I bought a 69 400 4-sp car and it was nothing but a rust bucket but for the $500 I got a complete numbers matching drivetrain.
$6500 should get you a daily driver in decent condition. I hope it all turns out for you
