Chrome sport mirror 3548731

This was mounted on my 69 cuda when I got it. No idea what it was originally on, that's why I posted the part# stamped on it.
The control bezel isn't for a B or E body. You might want to post the length of the cable as it somehow doesn't look long enough for a car without a vent window. The mounting screw hole spacing would be another measurement I would post too.
