Until I figure out how to post a pic, the best I can do is describe it as a silver, quarter sized adjuster with a hex head (I used 5/16") with some "teeth" on the bottom. If you were looking past the negative cable towards the back of the headlight housing, you see it. I had to move some wires, but it's right there. You can't really miss it.
It is directly under the "U D" marks and you could use a screwdriver to adjust it, but I found it much easier to access and requiring less turns to adjust if you just turned the hex head directly.
I didn't remove anything, just moved some wires on both sides. A decent small flashlight helps too.
Hope that helps. Now if I can just find the left/right adjusters.
