From what I've read, (never tried it)...the quick and nasty way is to set your mirror in the exact proper position

I suppose you could use tape and wood pieces for supports to make sure it's in the right place and doesn't move.

Then apply some crazy glue/super glue where the ball and mirror meet.

Others use 5 minute epoxy dries clear or JB weldand paint it silver...... but the secret in using these is to make sure your mirror is positioned right where you want it first.

.....other method involves taking the mirror off (without damaging) and adjusting the spring....google... floopy mirror repair,lots of ideas out there.

I have recently installed a new set of correct, chrome mirrors on the doors of my '64 CS.  To my dismay, they do not stay in position when I am driving and are easily moved out of position by wind and movement of the car.  Other than purchasing another new set, does anyone know of any "home" remedies to firm up the ball and socket?  Thanks in advance for any suggestions.

I had the same problem with a new mirror I bought for the Chevy II - I posted this last year on 2DoorPost, hope it helps...

Fixing a loose exterior mirror

I thought I'd share this since I know mirrors that won't hold their position are a common problem. I used a spare mirror that didn't matter if I wrecked it. I figured the mirror glass had to be held in place by some sort of adhesive so I put the mirror face down in a suitable sized coffee can and filled it with gasoline to just above the ball socket. I let it sit for 24 hours and the glass came out with little effort. What I found inside is in the first 2 pictures. The glass is secured by black silicone on 4 pads. The tension for the ball pivot is provided by the metal plate you can see. On this one the plate had separated from one of it's mounts. The design is the mount post is 'mushroomed' over the plate to hold it tightly in place (kind of like a rivet). To fix it I very carefully drilled out the post to accept small sheet metal screws. Be extremely careful here because if you drill too far you'll come right out the back. Also you don't want to get too close to bottom because the heat of the drill will discolor the chrome. The last 2 pictures are of the repair finished and the mirror is as tight as the day it was made.

Thanks for the responses to my floppy exterior mirrors problem. These are all good suggestions. I still have an old one that I can use for practice. Is there any special process involved in getting the mirror to stay in once the repair is completed?
