Here's my
.
On my '72 Challenger Rallye, the steel wheels I believe were standard items (You have to have wheels that come with the car, right?
) and I assume that even the hubcaps were an optional item as it was written down on my order form as an option.
Rally wheels and Magnum 500s and hubcaps were options according to my '72 Facts Manual. There were 14" and 15 Rallies, only 14" Magnums, all of which had trim rings.
15" chrome magnums as MJS73 mentioned are after market, however pre-1970 Mopar did have chrome 14" Magnum 500s. A lot of B-bodies had them.
