Do any old timers remember seeing these on a 1971?

These hubcaps came on my used 1971 Demon but the internet says that these are for 1972 Demons (and other '72 cars). So might these have come on '71 Demons late in 1971? Or maybe a previous owner put them on...

My 1973 Charger SE had those wheel covers. They were replaced shortly after the purchase with mags. I still have them in my stash.
