Russintin, I bought I think what your talking about for my sons firebird, it was 1/16 or so thick plastic fiberglass with cloth on the down side inside car. So far so good, very durable and had original look to it , one piece, if I remember it was $170 plus shipping. somewhat eazy to install, looks good, was very pleased with it.
happy holidays,
