Hey guys, I recently purchased a 1973 GTV 2000 from a gentleman that purchased it in California in the 80’s when we supposedly worked at an Alfa dealership. It has a metal panel sunroof that he swears up and down is factory installed but as I’ve seen plenty on AlfaBB it appears only dealer installed ever existed. That being said the vehicle is riding on 5 spoke original Cromodoras. All stamped made in Italy with Alfa center caps. I’ll post pictures when I have a chance but where the 5 spoke cromodoras a factory option in 73’? If so what is their rarity or significance. Thanks in advance folks. Any help for a new Alfisti is appreciated.
