Dart Windshield Interchangability

You can kinda see what I'm getting at here.
when people are looking for parts it is real easy to become confused with what you read on a web site, with what people tell you it is, verses what it really is. It can become difficult to get the right part.

We've always thought a coupe had a B pillar a post between the front and rear side windows, a hardtop did not.

Chrysler lists my 74 Dart Sport LM29 as a 2 Door Sports Hardtop but it isn't really like in the case of windshield glass, then it's a coupe.

Maybe it is because of the rear side pop out window. It is fixed and doesn't roll down, just pops out to the side.

Well in any case it is like the Duster and Demon
Not like the Scamp, Swinger, Valiant
