CB 750F Tank Differences

[motormayhem]

Are there significant differences between a 76 750 tank and the 76 750F tank. I know the filler is different but do they fit the frames/seats when a 750 tank is swapped to a 750f?

F tanks are a few inches longer than K tanks. You can swap them, but the seats won't line up.
