Sub,It will work, but you will have to use the the cb750 peg and arm, mine were from a 78'. But I would say earlier and later models are probably the same. Remember though, on the right side, it will be right up against the header,so you will have to "adjust" the pipe and or put in some type of insulator, HOTFOOT!!, and your heals are going to be lower on both sides in relation to your gear shift and brake peddle.
Good luck,let me know,
Dan.
