Headlight adjustment (2nd gen)

I have a question that I'm sure someone can answer here. Which adjustment screws need to be adjusted for vertical (up/dwn) movement of the light? I noticed there are two that sit diagonal from one another...one at the top and one at the bottom corners of each HL assy. Thanks in advance!

 

If you loosen the screw it raises the light.
If you tighten the screw it lowers the light

I've only adjusted the screw labeled B in the diagram. I have a leveled out plus 1/2" higher and I did close to 3 full rotations of each screw ( driver and passengers)
Make sure you mark the screws before your u turn them so you know have far one ration is and to get a equal adjustment on both like lights.

 

Thanks so much!
