Pickup up a decent YT60 Tri-Zinger - Any body have a seat or seat foam I could buy?

[sjohnson]

My new 1985 tr-zinger is missing the top half of the seat. The seat pan is there and is good, but there's no foam. I was hoping someone here had a spare seat I could buy.

If you have a seat or seat foam that you would like to sell please message me! Thanks, Scott
