I am looking for an old seat for a 2001 to experiment with....
That's going to be a tough find. The 2001 had a one off seat that is now sought after by collectors. Lol, just kidding, all of the seats are the same except color. Don't know what kind of experiment you're doing, but here is an old beat up one you could probably pick up for cheap that may work for you if you're planning on recovering/refoaming anyway. Or maybe a member on here has an old seat laying around.

The one listed for sale is off of the extremely rare 1986 model. Hopefully no one will recognize it's rareness and bid you up<G>!
