I threw a complete set of excellent 57 seats away in a dumpster a few years ago.
The springs were in perfect condition and the upholstery was flawless. They sat in my garage for years. I tried to sell em on several websites, but no takers.
What kind of car do you have, and where are you located? I have a set for both 2dr and fordor, front and back. They are cores but springs and frames are in pretty good shape. I can ship on greyhound for cheap. Give me a call 208-755-0407.
