Ah, you had the table that had your items identified and the big label saying 77/78 Honda CB750 parts,good for you,I wish more people had taken the time to identify what they had.I really hate digging through boxes full of greasy parts.
I hope you made some money,your parts all looked in good shape..unfortunatel I was scrounging for '72 CB750 parts or '77 Suzuki GT 750 parts...
