so my right zkw headlight is all messed up. im talking about the adjustment. so the back adjuster, the one behind the highbeam, the back popped out and i realigned and put it back in. but my problem is....i am adjusting it downward and teh screw or whatever you call it pops out. so there is no way for me to adjust it down any further, i have to use the plastic screws to point it downward which makes it look bad. does anyone have any tips. thanx!
