I guess that I am old fashioned, but I did change the factory 86 clock in my spyder to analog. It was over 18 years ago, but I found the clock in a factory sales pitch...can't remember the model car. The replacement was a direct exchange as I recall. The hardest part was to pull the old clock. It took micro-screwdrivers, and a lot of patience. The clock is better, and easier to read in sunlight. Check sales lit from the late 60's to early 70's if interested. Center of the dial has the Alfa logo.
