Hello again gentleman,  so I bought a 72 with a seized engine.   I've read it's fairly common from car siting for 10+ years.   I've read about the mystery oil and ATF, coke and even read about towing the car and popping the clutch to free up engine.  I just received the car last Friday and What I'm trying first is mystery oil soak.  It's been 4 days and nothing.   I'm thinking about pouring some HOT ATF and trying that.   Has anyone had success on freeing up a seized engine?    Also,  I need ideas for trying to turn the crank pulley instead of just the bolt, I'm worried it will break.  Maybe even taking starter out and try turning the flywheel with a pry bar.   What do you guys think?  Greatly appreciate your time guys
