Anybody have a source for round 4" convex mirror which has center mount on a post. I found 5" no problem. Joe's racing mirrors are only 3" and look a little small. 4" would be perfect. I've searched google like crazy with no luck.

http://www.hrpworld.com/ HRP sells Longacre. I believe they are a partial sponsor of Bob D's, and right down the road from him.

I had a hard time finding a ~5" flat mirror (didn't like the full convex on my drivers side). I ended up finding one at a golf cart shop of all places. Much cheaper than the longacre stuff to boot.

Unfortunately this one doesn't list the size, but it gives you another avenue to start looking.

This is similar to what I have...
