Hi Bob,
My car is at the other end of the scale, a Giulia Veloce 1600, built in '65, sold and titled as a '66 with some of the first Duetto's. It also has some strange features. The photo's from you would be the drilled and threaded holes in the left fender well for the later Veloce air cleaner, hood, gauges and general engine compartment layout. Most of us are aware of the tail lights, but thats a good one as well as any badges of lack of them on the trunk lid. The PF numbers, again, or lack of same, on the trunk floor, trunk lid, right trunk fender gutter and hood. Being a senior as well as the owner of my car from new 43 years ago, makes the physical development of these cars equally interesting to me as well. I have seen several cars like yours, but was not immediately aware of the extra underhood holes, Veloce air pickups with blocked holes, and other details. Thanks,
Gordon Raymond
