Basically you are correct. Differences are the hood, header panel(the inner park lamps are unique to the TC), and bumper cover. Except for the red trim in the body side moulding, all other panels are the same. This is for the '87-'88 models, earlier years had the std hood(no intercooler). Also some years had body colored grille instead of chromed, in addition to the driving lights in the bumper cover.
