I'd tell you that any '81 or later Honda twin piston ones for DOHC will fit but only 90% convinced of it myself. Not sure about spacing or the bracket bolting 100%. The calipers fit the disc size as they are identical but they don't rub as deep into the disc, ergo, the scrub pattern is narrower. Probably do, I just can't say for sure. One reason is that the '81 and later forks also spread apart another .300" or so and while for stability (wider wheel used on later ones) may affect the disc issue too. Thinking not but you would be the test guinea pig there. Better calipers of that type in your case would be the ones that do NOT attach up to TRAC, the antidive mechanism used on later ones. That's because the TRAC ones use slightly different mountings that pivot to work the antidive. You'll be looking for ones that do not do that, or mount solid.
Look for '81-'82 CB750F, 750C calipers. The 900, 1000, and 1100 all have TRAC as does the 750SC Nighthawk. TRAC can be identified by a rectangle shape molded into either one or both of the lower fork legs at the back, one of the caliper mounting bolts will attach to the fixture bolted to that rectangle.
