2 passenger seat for a 82 Kz1000P

Just wonderin if any one had any idea as to what bikes might have a seat that would work with my bike. I am making a seat out of plywook and several layers of really good foam padding. and the back of an old leather couch. but my solo seat is in bad shape as well. I was thinking I could probably find a seat that would fit off of another bike. any one have any knowledge here?

I have a seat off my 1977 kz1000 might work for you.

ive read that the 82 ltd seat is almost a bolt on i have a decent pan from an 82 1000 with useable foam but the cover is trashed
