Sun Visors
There are two types of sun visors. The one to look for has stitching around the perimeter. Without the stitching, the inside stuffing soon begins to lose its shape and they look awful. The perimeter stitching holds the stuffing in place and they remain looking good for years. The visors that I have came out of a mid-80s Spider and they still look good.
Yes, Fiats DO have the metal connectors and they do hold up better.
The Fiat and Alfa visors are interchangable (I have both a couple of Alfa Spiders and a Fiat X1/9). Quite a few of the Fiat guys will use other visors from a local U-Pull-It which can also be altered to fit. One guy that I know had to yield to the desires of his better half, who insisted that if she were going to ride in his Fiat, it had to have a sun visor with a lighted mirror, so that she could comb her hair!!
