Hey I have an 89 ranger whose mirrors move every time I drive down the road at 60 mph. I did not see a way to adjust them. Should I go buy a replacement mirrors that look like the stock ones or should I go buy some good aftermarket ones.

 

I put a zip-tie at the base of the mirror where it swivels, and seems to work really well.
