what seats will fit my kz 1100

i need to replace my stock seat on my 1981 kaw kz 1100. the seat pan has rotted away. i am wondering if there are seats from any other style bikes that would fit this bike. i am not a big fan of the box seats that came stock with these bikes.

there is a 1983 kaw spector 1100 ltd seat on ebay right now that is a much better style than mine, but i am not 100% sure it would fit....

has anyone else changed out your seat with something like this ??

any help will be appreciated.....

Bump!

I'm having the SAME question now...when the feeling comes back to my butt, I may sit down again
