I'll post side by side pictures to note the differences when I can.
I received a pair of correct Plymouth panels from a very cool and friendly Moparts member (Hemirdrnnr).
At first glance I didn't see the difference, because I was looking at the overall length, which is actually the same. The difference (as shown in the photo below) is that the Dodge panel is taller / higher. This explains why my pop out window latches are making contact with the incorrect Dodge panels and won't work / fit correctly.
Thanks again to all involved in finding the much needed answer to this issue!
