Yes, basically the "painted wheel & dog dish hub cap" was STANDARD equipment & included in the "base price" (14x5.5", 14x6.0", 15x7.0").
If no OPTIONAL wheel covers or wheels were ordered that's what the car ended up with.

The STANDARD wheel would be (14x5.5", 14x6.0", 15x7.0") based on model and/or upgraded due to other OPTIONS.

A '71 'Cuda with upgraded to E60-15 tires ONLY (NO W21 "rallye wheels"), would have painted 15x7.0" wheels. Body color before ~4/1/71, black afterwards.
