Welcome to the forum! The '69+ 2 door Coupe (Posts) have different inner door structure and window regulators than those used on the hardtop door. There is also differences in the inner 1/4 rear window area and in the door jamb area, no screw on plastic vent in the Coupe body...that is only the smallest difference.
Would have to study between my '72 Coupe and my '72 HO hardtop to nail down exactly what's different in the roof rail area. Another difference, if your '69 Tempest a heater car, it like all factory non AC '69-72 2 door Coupes, 4 door sedans, and wagons, the molded dash assembly's do not have the vents on the outside edges of the dash and no structure in the upper dash area for hooking up the vents, In other words, no upper level ventilation, AKA AstroVentilation. If you were to substitute a dash asm out of hardtop, the outer vents wont work without R&R'ing the welded in under dash structure. The reason for no AstroVentilation is all 3 of these body styles had vent windows.
Not sure how solid a body it is you have, or in this body modification direction, or how extensive your metal working skills are, but can relay that really nice body '69-72 2 door A body Coupes are desirable for sleeper builds and stock appearing builds. Many times one will see such 2 door Coupes built with much stronger than the top option engine offered for that year. Combination of lightweight factory bench seat £ spartan interior, just keeps the weight down. Due to the Post and full door frame construction, such Coupes are much more rigid and desired for 1/4 mile cars. Another plus is the same year 2 door Coupes are always lighter than same trim level 2 door hardtop. Its also possible to build up such a Tempest or LeMans Coupe into something quite desirable, where as cloned GTO's only get so much interest. Hope this answers several of your questions, have more, feel free and ask, working on several of each body style.
