My '54 pickup has the side peep mirrors with curved arms. They come with straight arms, too, I think.
The driver's side mirror works very well but I have not been able to find a location that works on the passenger side door (can't find a place where the mirror can adjust for a useful view).
Mine came from Chevy Duty - you need a metric hex "key" to tighten them (or you will either strip the stop screw or not be able to get it tight enough).
