73/74 sail panels should interchange fine.

The catch is the rear interior panels.

74 has a two piece (for the retractable shoulder belt assembly) that the previous third gens do not.

Also, if you got the base coupe, your windows do not roll down, and the panels do not have holes for window cranks.


I have a 74 RR that I got a free 73 Satty interior for.

I have holes for window cranks I do not need, and had to cut the panel to accept the seat belt inserts.

Your mileage may vary as I have heard some rumor that non rolling and rolling rear window body styles may have different sail panel shapes, but the shapes look exactly the same to me.
