66 Dart GT HT Whatsitgonnabe?

Looking at your booster and MC has renewed my interest in tearing mine down and going through it. The booster didnt leak when it was in the parts car i bought and took it from. Car ran , brakes worked good. I have actually taken the diaphragm rubbers when going through other boosters for project cars and renewed them a bit with silicone based vinyl protectant. Nothing as old as this one though.
