I'm so glad I saw this thread. I have to adjust the headlights on my A. A friend of mine, who owns a '31 coupe, told me to shine the lights on the garage door and adjust them. I know that works for modern cars, but I like the idea of using my 4' carpenter's level instead. It is more precise than eyeballing the adjustment. This information means I can adjust the headlights without even taking the car out of the garage!!
Thanks!
