15" wheels were optional for the entire AD (47-55) series. I don't know of anywhere that sells "correct" wheels, as in exact reproductions. But wheels are available along with hubcaps that are slightly different than original.
The original hubcaps just cover the lug nut recess. Your wheels would take larger hubcaps that fit over the bulge outside the lug nut recess.
