i think a factorylooked more like a fulll piece, i cant explain it without pics, but my 87 has a non factory i beleive, pay attention to the top, theres a littler strip of metal with no glass, on the others, they go all the way to the top
factory, window frame and glass go to the top
non-factory(i beleive), window doesnt curve or go all the way to the top, and has a strip up top
