It seems when my truck was built in LA, CA, back in the eighties, there were junkyards full of Porsche 944s, because seats, mirrors and an electric sunroof were all installed on my '57.
Click on my avatar, to enlarge the photo and see the glass side.
The mirrors are heated and electric adjust. I use small round stick-on convex style on them, too.
My mirrors could have been placed better, but I use the inside rearview for all but backing up.
I found a passenger side replacement on Ebay for $50 delivered.
