Have had 3 types on my Tacoma. This is the newest that I got to replace one similar but different. They have to be screwed down tight or will fall/blow off at highway speeds. We use CIPA mirrors that fit over and snug onto the side mirrors for our Tundra, but they don't make that style for the Tacoma.
