1968 Headlight aiming adjustment screws

On the horizontal adjustment screw does turning it clockwise make the light move up or down? Also on the vertical turning it clockwise makes it move left or right?

Easiest thing to do is try it and see which way they move. I did mine last year but don’t remember how they went. It’s rather simple once you get going.

That’s what I did, just starting playing with it and it was pretty easy. Last night I drove it in full darkness for the first time and the headlights were way out of alignment. All good now.
