I finished my vitaloni California on standard mirror stalks mirrors..
I took the vitaloni's apart:

See the twisted mirror base?
Took the base off with a saw, and smoothed it a bit:
Then I dismantled a standard mirror. I found out that there's a bolt behind the glass!
So, they came apart very nicely:
Now that makes a great new base for my Vitaloni mirrors:
I pointed the standard stalk forward instead of up.
On the car:
I am happy with it!
I allready did some test-drives, and allthough they are a bit smaller then the standard mirrors, they are still usefull.
And I don't even have to paint them, the sawn-off bit is hardly visible.
