I'm like you. I like the hardtops myself. If you are not going back to stock then you may want to sell the entire removed SE parts as a kit on E-bay. Some people like it.

The panel for the opera window is plastic and screwed to the body IIRC. Often they rust under the vinyl tops so until you remove the roof & panel you may not know.

I forgot the upper inner panels will need to be changed but they are the same for any 2 door 73/74 Satellite,Charger,Road Runner etc. Maybe even 71/72.

Lower panels are different in 73/74 because of the retractors.
