You can't adjust these headlights side to side. There is only up and down adjustments available.
Mind fit something like yours, and I'm able to adjust them up and down so they are aimed properly.
You aim the low beams first, and then the high beams will be aimed correctly. If the high beams are aimed wrong, you might have a bad fit for the bulbs to the retainer ring.
Some of the aftermarket bulb retainer rings are made to allow other bulbs than what the OEM were ment to take, and this can cause problems with some bulbs alignment in the assembly.
This is what mine looked like with the stock grille and Denali headlights:
Here they are with my aftermarket grille:
It still has a bit of gap.
And here is what they are supposed to look like on a Denali/C3 truck:
Ours are never going to look that close.
