I was 10 years old when I first saw one of those tops. A cousin bought a Challenger with the Mod Top.
Not to say that it's not possible , but I've never seen nor heard of Dodge continuing their "Floral Pattern" for 1970 . Who knows ? Anything's possible !
First time I can remember seeing a Mod Top was in ca.1972 or so (when I was 2 years old) . The car was a 1970 Barracuda . I'd see it frequently at the local mall , in the parking lot by Hinshaw's .
I'd asked my mother , "Why did someone put wallpaper on their car ?".
I'd not seen the Dodge "Floral Top" until sometime in the 90's ...
... at a self-serve salvage yard , on a '69 Dart

. I saw remnents of it wedged in the driptrough moulding and thought , "What the heck is
this ?!?".
I've long preferred the Dodge pattern , as it looks more like a Peter Max illustration .
