HONDA, OEM, Used, Side Stand, CB750 etc., 50530-341-670 + screw 90108-2883-000 Y4
This came off a CB750 K2, but will fit other models (and other bikes). Honda use different part numbers for the K0 and K1 but the part appears to be exactly the same.
This is not straight as a die, so may need further work? hard to say without fitting it, which I can't.
Cheers
