Trim Identification Needed

So if a 4 door or 2 door post has a taller roof line, does it have a different back window as well? For that matter, does the back window change throughout the years to any degree? Still trying to figure out what the lower rear window trim is off of. Looks like it's a little flatter curve than my 67 hardtop. Didn't know if the taller roof line of the 4 door might have a shallower bend or if it had a different back window entirely.
