Here's a couple of pics of the Western Jr mirror on my 59 f100 4x4. Sad to say but I'm missing the passenger side mirror. Not sure if this is original, trying to get educated on this. Mine looks to have a "fluted" aluminum mirror housing.
Mirror size is 6" x 10-1/2". Someone riveted the mirror onto the door and I need learn how they are correctly installed. Funny but out of the hundreds of things that need attiontion on my rig, the mirrors are at the top of my list.
Thanks for putting this post up.
