They are a 69 Camaro coupe, standard interior, armrests for fold down rear seat with filler panel and qtr interior panel that fits above the armrests.
You can see the outline of the filler panels in the rear of the qtr panels. The fillers were hard to find until they started repro-ing them
Convertible versions of the armrests are shorter and no filler panel, instead a big panel to hide folding top mech. Same for qtr, panels, verts are shorter.
