Where can I find the foam seats for a 1999 Yamaha XL700 wave runner?

Question

I'm NOT looking for a complete seat. I have the seat already and new fabric to recover the seat. I just want to replace the foam cushion. Where can I get just that part of the seat without going through the dealer?

Answer 1

What size?  I might have the cushion portion.  www.jamminjetskis.com
