1966 Dodge Dart GT Factory Ride height?

I need help again on my 66 Dart GT 273 restoration. When I adjust my torsion bars, what is the factory ride height? I have P195/70R14 tires on the car. From where to where do I measure this height? I know that this adjustment will change the front end alignment? I am taking it in tomorrow for the final front end alignment. If anyone can help me with this, I would appreciate it. Thanks in advance.
