Factory Ride Height 70 RR

Can anyone tell me what the factory ride height should be in the front for a 70 Road Runner ? Also, where do you measure from ? I want to get an alignment done, but need to get the ride height established first. Thanks for any help that can be offered.

Sorry, I'm way away from my manuals but the measurements are from a few points on the lower control arms. An old Chiltons manual has them. Here's what mine sat like new, before I started monkeying with it. It was pretty high.

Thanks for the pic Dodgebrother

Anybody else want to chime in?
