I bought new brackets and these stock bulb housings separately. Am I missing something. I assume the screw is for lining them up but the holes seems to big, should there be something on the other end for the screw to go into?

 

This is a little hard to explain without a pic..can't get one now (dark outside). It looks like that you may have the wrong lamp/bracket combo here (as in..a right hand bracket with a left hand light housing). anyway, the screw goes up through the black plastic piece (large hole) and into the fog lamp lens for adjustment purposes. When I replaced one of mine, I had to remove the screw and put up through the housing tab into the lens assy. I hope you can understand what I'm trying to point out..if still needed I can get a pic when it's light outside

 

HAHAHAHAH looking at it Now that totally makes sense. I completely understand. Thx for the quick reply

 

Glad I could help, your welcome!

 

I know this was already explained, but here's a pic if it helps.
