Hey Nancy, I have 2 seats from that era, one a 2005 vintage that is in "perfect" shape although lots of miles on it and another from 2006 that has a broken brass snap hook that attached it to the kayak's forward cleat, could easily be fixed. I've replaced both with what we believe to be better seats so these are available to you if you want them.
Since they are old and since we've certainly gotten our fair use of them I would give them to you for free just to see them be usefull to someone instead of collecting dust.
We live in the Tampa Bay area.
Maybe we can arrange something... I don't want to pay for shipping myself.
