the answer to your original question is: no
Mod Top was only available in 1969 for the following models:
Satellite (blue)
Barracuda (yellow)
Dart (green-roof only)
Coronet&Super Bees (green-only)
1970:
Barracuda/Cuda (yellow and blue)
That is it from the factory.
There are more cars out there but the roofs have been added by owners or dealerships.
1971 Imperial roof with flowers in UNWANTED by Mopar. It was a mistake by the supplier of the material. It was an old print and they painted it burgundy as it was supposed to be. That is what you can find in the colour&trim selectors. But in the sun it startet fading quickly and the flowers showed up. As a result the top got cancelled midyear. So if you see an Imp with that roof it was NOT planned to be.
