And seat from a z1 or a kz 900 or 1000 from 1973 to 1980 will work, the only differences are the z1 has a round tail so the z1 seat may not look right on your bike, and the other difference is the locking mechanisms are different, the z1 has a unique one, but im pretty sure they could be swapped out.
