Ride height for 68 Valiant

I have a 1968 valiant with a 225 slant 6 and it is a 3 on the tree. I am currently trying to align the suspension and I can’t find anything on the factory ride height from the floor to the arch of the wheel well. Any help is appreciated.
The factory doesn't measure ride height that way, so you won't find that number in a book anywhere. So, set the ride height were YOU want it, then have it aligned.
