Sail Panels?
You can use the metal panels from the ‘70-72 cars. The notch for the latching hardware has to be made larger for the later latch mechanism, and you need to replace the rear interior panels as well because the height of the rear panels is different. You also have to use a sail panel section to tie into the headliner like the earlier cars, I just used a thin piece of abs sheet. It sounds like a lot, but it’s all pretty easy. The new interior panels below the windows were the most expensive part of it. But finding intact plastic sail panels for the 73+ cars is nearly impossible, and shipping them is insane both for the cost and the potential for damage.
