Getting back to the vents for a moment, the parts books show 1750s with 2 vents and the 2l with 4. However, there have been posts on this BB from 1750 owners stating that their cars have 4 vents.One possible explanation is that during the 1750 production run, Alfa changed the design from 2 to 4 and just started assembling the cars with them when they (the 4 vents valance) became available.
