Is it possible to tighten a hooded side mirror on a '58? There's the screw on the back that I've tightened all the way and it helps a little bit, but the mirror doesn't really stay in place. I've seen others that are almost rigid and you have to use force to adjust them. I didn't know if there was a way to disassemble/rebuild the mirror versus spending almost $150 on a new one. The one I have is in good condition, it just gets out of alignment any and every time I have to mess with the car cover or barely touch it.

Thanks in advance,
