Differences Between '67-'68-'69 Barracuda Notchback/Convertible Trunk Lids

To clarify: convertible and notch are the same, but all three years are different. The main problem is where the 67 lid has stud holes, the 68 would have exposed painted surface, and vice versa. The 69 panel covers the entire rear surface, so you could use either of the other two lids on a 69 and just have extra holes hidden behind the panel (of course, you might have water intrusion issues if you don't at least fill them with caulk). But otherwise, you would be looking at filling and finishing somewhere between 10 and 20 holes. Not a trivial endeavor.
