Head lite adjusting

[Kahuna]

I have a 32 Ford with Original headlamps. The headlites have the new Drake reflectors and bulbs. The lights are great!
Here's my issue:
I took the car to a shop that has the old style headlite adjusting equipment, but he couldn't get the things to adjust using it.
So, I'll try the old method of a wall at some distance and height.
Does anyone have the correct original distance and height that Ford used?
I've got an area that's level that I can use.
Any help appreciated
Thanks
Jim
