Not a 63-4 Impala-----but-----probably a 63-4 BelAir.
Not sure that any of the other Chevys had 2-tone wheels except the full size cars.
A nicely equipped BelAir would have that wheel, but still use the upgraded BelAir horn ring.
In the 59 60 cars----there was the BelAir/Biscayne wheel and only the horn parts were different. (Belair=chromed with partial ring-----Biscayne painted horn cap) Impala had it's own wheel from 58-60
(It might be noted that the BelAir/Biscayne wheel was also used on the Deluxe pick-ups from 60-66 using the BelAir horn ring & Cap)
I think in 61-2, all the wheels were the same style, but the upper class of the Impala and BelAir got 2-tone wheels. (base cars did not)
