2004 2500HD Headlight adjustments

I adjusted the torsion bars on the front of my 2500HD 4X4 to give me a little more tire clearance. Now my headlight beams are too high. How do you adjust them?

Don't really know on the new grilles. On my 02 there are torx screws on the headlight housings. The top on moves them left and right and the bottom one moves them up and down. Probably the same setup on yours.
