I like the look of the ribbed backside, goes well with the hood side strip trim….

Came to me mounted with a bracket to the center bar of the windshield which I don’t recommend, every time I crank the windshield the mirror is out of adjustment.
No sheet metal on these trucks is thin, self tapping screws or sheet metal screws will be fine, for extra bond put a bit of adhesive caulk behind the bracket first.

Thanks for the input. That was the one I picked out if I was going with a stud mounted version on the adapter. I will go with a simpler one that mounts to the headliner.
