MB,
The Vitaloni Californian does not mount on the window as you suggest, if somebody has mounted them that way, they manufactured their own mounting system.
If you're looking for a small attractive mitrror that mounts to the window check out the mirror sold by Wilkinson.
Chris (macman) recently installed mirrors similar to the Californian on his Pantera, sold by Southern Rods and Parts, they're called the Carolina mirrors. Here's the link:

And below is a pic of Chris' Pantera.
