I'll take a stab where your fender trim is concerned. If your car is a 71, it could not have been an SE "model". In 71 it could have been ordered with one of the "packages" that were created by splitting up what used to comprise the "SE model". The Challenger SE Moulding Group (code A63) got you the chrome trim which would be found on top of the rear quarters just outside the side glass, trim on top of the doors just outside the glass, rear edge of the front denders, and at the rear of the hood.
There was also the "Formal Roof Package" (code A78) which made a vinyl roof necessary and got you the smaller rear window and, i believe, the felt-on-perforated-board headliner and overhead console.
Do you still have your fender tag? I believe that since A63 and A78 refer to a "package" or "group" instead of individual items, they should show up there if that's how the car was ordered when new.
