What other Honda CB### Seats fit on 750?

[Jason R]

I've been searching long a hard for new seat&pan for my 77 CB750K.  I'd like original but there's nothing in my price range.  I need to expand my range of options by considering seats from other years and models.  Does anyone know what other seats will SURELY fit my bike...as in flush with the tank?

switching hinges isn't a problem

Thanks Guys
