Looking for a new (Different!) Seat

Hey guys,

I've got an old cracked busted up seat on my 76 KZ750B. It's also the style that has the passenger up a good 8 inches higher (which I hate) and no hold strap (better word for that?)

I was wondering if any seats are interchangable for this one from other years or other styles. I'm looking for something like this...

There is one for sale in the classifieds, I just inquired about it and the seller said he wanted $50 for it.
And it is for a 76-80 750 twin.
