The outer roof skin is identical. The inner structure of the later cars doesn’t have the tabs needed to hold the roof bows because they used the one piece headliner, but is otherwise the same.
The one piece headliners are just held in by the rear view mirror, visors, dome light and rear coat hangers.
The issue I think you’ll have is the sail panels, since the one piece headliners were used with the later cars that had the plastic sail panels that went from the quarter windows all the way back to the rear glass.
With the metal quarter widow surrounds and the one piece headliner you’ll have to make some kind of sail panel to cover the area between the metal panel and the rear glass. I just used a flat piece of ABS plastic I trimmed to fit because I use the metal panels on my ‘74 with the one piece headliner
