Ok, I feel really stupid for asking this, but how do I install the headlight trim rings on my '49? They came with 4 clips, 3 different styles. I see I need a screw as well, anyone know what size? If someone can explain how this all works, that'd be great! Thanks!!

If you can't fix it with a hammer, it's an electrical problem
