I remember when Cragar S/S wheels came out in the later 1960s. The "In" wheel as everybody that perceived themselves as "car oriented" had to have a set on whatever they were driving. THAT got boring! I was not that excited about them to start with. But the Magnum 500s, THAT was a nice wheel! Not sure why Chrysler was "behind the curve" on 15" sizes and narrow 5.5" rim widths? Ford put 15x7s on their HOT Mustangs of that era.
Some wheels, by observation, just seem to be "accepted" on Chrysler products if the particular ones never were available on Chrysler Corp vehicles. Notably the Magnum 500 15x7 4.25" backspacing full-chrome wheels.
To each their own . . .
