When I built my 37 ford, I put the simple 3" round side mirrors on it thinking it would be sufficient, and they looked nice. They have been effectively worthless. First off, they vibrate, so you cant really see anything, anyway. Secondly, anytime someone slams the door a little too hard (including myself), they get out of whack. Even the wind seems to throw them off. They just won't stay put.

I felt like I wanted something a little bigger, but there really arent many options out there. Seems like all of the "street rod" ones are tiny. What can I do to make the ones I have more useful?
