That's the correct air cleaner for a 383-4 in 65 . . . but there are some mods on the car (note the dual master cylinder). Looks like a nice car, but I'm not that wild about the color. Even though the dark green is listed as factory color in 1965, to me it just seems to look better on a later 60's/early 70s car. Agree w/ rapidtrans on the skirts . . . I always think they look odd on the Monaco. I think it's because of the wide, ribbed sill molding - it just looks like it stops so abruptly in front of the skirt. To my eye, the skirts seem to do better on the Polara/Custom 880, w/ the thin molding.
