I won't swear to it, and I'll deny it if asked, but ... yes, I think so.
I have a '69 2 dr sedan, I know the windshield and rear glass, headliner, pretty sure I remember the rain gutter is same, so with that much interchangability I would take the chance that the vent windows will work.
Nothing like a definite answer, right?
Edit:
OK, I have 67, 68, and '70 parts books. Just went out and looked this up.
All three call for same part #s for vent glass and rubber, for 2 and 4 dr sedans, Valiant and dart.
To venture a guess, I would say the vent window stuff probably remained the same on the 4 dr til the end.
Hardtop model tho, I didn't check, But due to the difference in the windshield I would say the vent glass is also different.
