Answer
Vernon, try the http://www.sohc4.us/ site for assistance.

Are you looking for the seat and rear grab rail or ? UK owners call the rear fender a rear mudguard, so there is some room for interpretation here.

The 77-78 550 and 750 models had some pretty different styling and design changes, so I doubt that a 78 CB550K seat would bolt up to a CB750K2. Make accurate measurements of the seat hinge dimensions, etc. so you can compare your chassis with other seat pans.
