True Classic
Actually those ARE the Italian Vitalone mirrors. A Chinese company makes them for Vitalone and Italian law allows the company to say "made in Italy" despite not really being manufactured there. Same for most products sold from most countries. It's a modern world full of surprises.These are a Chinese copy of the Vitalone California, right down to the "made in Italy" on the base casting.
I also have a set of them to mount on my next X project build. I agree, they are a classic style for these cars. I like your mounting arrangement (most aftermarket mirrors come with crappy mounting hardware). The stock X mirrors mount into a reinforced area of the door. So if you used the same general locations then the mirrors should be very solidly affixed.
The next time you take the car out please check out how the mirrors function and report back. There's been prior posts saying these end up located in a bit of a awkward location for best visibility (if mounted in the stock location). I believe it was noted they should be moved slightly rearward from the original mounting point. But others said otherwise so I'll be interested to hear what you think. Where are yours relative to the original holes?
