My side mirrors do not stay in place.  Closing the door moves them, the wind of a passing truck can lay one flat!  I figured they where old (which they were) and bought some new ones on Amazon - they are K-Source OEM mirrors - same thing.  So what's with these mirrors?  I could get them in the right position, pull them off, and tighten the nut under them but that didn't work with the old ones and I don't think it will work with these.  It's both annoying and dangerous to have to adjust them every time I drive and again every few minutes when I drive.  

Is there another mirror that is good?  Is there a trick to get them to stay?  Suggestions?  Help?  Validation?

Thanks,
