Door mirror clips
 

So I have done the brakes, replaced the A/C compressor, changed the rear-end and valve cover gasket and she is doing great. Only one complaint, my drivers side mirror vibrates after 45mph. I'm not sure if folding mirrors came factory on a 1992, but it appears there is a plastic piece that holds the mirror when it is not folded. my clip appears to be broke and is probably the cause. Anyone know where I can get one?

Junk yard, and they weren't really folding. But could move in towards the window if struck. To help lessen the Damage.

No joy at the local JYs. Living in the mojave has its perks, but longevity in plastic is not one of them.
