I have a 1980 cb750k tank you see here that i took off not long after this pic.You could also do this and use a honda shadow tank.

Yep same frame and motor.I offered the original tank to someone a couple days ago for $200 but if you need it and he does not contact me in a day or two you can have it for the same price plus shipping.
