I already looked at two auto salvage places. They had fabric/cloth seats and hardware for about $50. Although the seats they had to offer came with rusty mounting hardware, had stains all over them, broken glass on them, decaying leaves, animal crap, etc.... since the cars they came from had no windows and were available to all the woodland creatures to use when they wanted to recline..... :>)
Anyway, I decided having a nice Mame driving arcade machine cabinet in my living room with a real automobile used car seat would look quite out-of-place. I already did the impossible by conviencing my wife to allow me to keep the cabinet in our living room, but I doubt she would like a used beat-up car seat from a 82 mazda mounted on it.... :>)
