I was at a show n shine a couple weeks ago.  The car next to mine was a '67 Mustang.  Nice little car.  I was sitting on my lawnchair behind my car when I noticed the reverse light on the Mustang.  Hmm.  I measured it and mine and they're awfully close.  I'm pretty sure it'd fit.  I didn't get a chance to measure the screw holes, but they look to be very similar.  Even the ridges look the same - internal concentric circles.

I'm betting these '67 Mustang lenses are re-popped..

Here's a photo of the Mustang lense.

I know - a MUSTANG part of my Beaumont???

Better be doubly sure.......... maybe the Mustang was using a Beaumont lens.....

That is a great tip. I know Ames Performance offers repop 66 Tempest / GTO backup lenses but instead of the coincentric rings like the Beaumont, they have horizontal ribs (correct for the Tempest / GTO).
