I have never seen anyone selling cloth seats. As he said I would just keep your eyes open and put word out your looking as I could not give mine away when I replaced them. I ended up stripping the track and the lumbar to sell and trashing the rest.
Which cloth is it? I had a 00 gt with regular cloth like most other cars. But I saw another mustang a few years back with like a corduroy type dark grey material. I’ve never seen it before or since.
