I guess the question is.... Where (how) do you get the lights aimed more or less where they are supposed to be so you have a starting point to finish the fine tuning?

Perhaps this diagram from the 1960 Chevy Truck Shop Manual will prove helpful:



Just park the truck 25 feet from the measuring surface, and make sure it is on level ground. I find it easiest to block the low beam lamps when doing the high beams with either cardboard or a helper. It can also be helpful to block everything but one lamp at a time if they are really goofed up in the beginning.
