For the umpteenth freeking time...
Raydyots
Raydyots ARE period correct.
Once you drill the holes for the bullets...you will have them forever.
The frame mount provides a better field of view over the rear fender.
The convex (if they are true Raydyot convex and not some substituted Pep Boys convex) are slightly tinted and work great for the middle mirror...especially at night (I have no problems with car lights behind me).
The Buckley Mirror Mount is the best ever made. The mfg of them is a bit of a unusual character who makes them only when he damn well feels like it, and he hasn't felt like it in quite awhile. You will end up with second best no matter what...
