Mirror passenger side..

Thanks, where can I find one like this one to buy... Not really concerned about originality when it comes to mirrors.

I do have one question that I never asked and I think now this would be the perfect time & place to ask.

With the mirror is in its original place on the door, is it supposed to touch/rub (when you open) the vent window against it.
Or is it supposed to just slide open and pass the mirror with not even a brush against it ?
This is when you are opening the small vent window all the way open.

Thanks to all.
