Were VITALONI CALIFORNIAN DX mirrors an option on 1979 308 GT4?
I don't know if they were a factory option in 1979 (I'm sure señor Garvens will ), but recall that it was a popular upgrade on the earlier cars and cars lacking passenger side mirrors. I had the original Cromodora Astro III mirror on my first GT4 back in the 1980s, and replaced it with a pair of Vitaloni Californians. Oh how I wish I had saved that mirror.
I like the Vitaloni California look better than the oem installed on my GT4 but I'm affraid to take away from my car's originality if I were to install passenger and driver Vitaloni Caloifornias.
