1966 Dodge Dart GT Factory Ride height?

After you give up on the factory procedure.

I just measure from the front k-member bolt to the ground. Equalize the other side and tell the alignment shop not to touch the ride height.

What this measurement should be is a judgement call. I set the ride height so the tire is framed nicely in the wheel well. Which puts the front bumper just below my kneecap. As you can tell, very "factory engineered" and "by the book"
