starter clutch: where to find???

Hello everyone,
I finally have enough information, and know how to attempt this repair, and thank you for all the help I recieved here. Now I have one final question. Where do I find the parts to make the repair? I have searched the internet and I have not had any luck.
Thanks in advance.

to answer your question, we need to know what model bike you have.

sorry, that would help.
Its a 1980 KZ750. Not sure of model as it is an engine I put into a chopper frame.

If it is a KZ750 Four, I replaced my starter clutch on my Zephyr 750 '91, a KZ750 four, and bought entire clutch from Bike Bandit. I'm sure Ron Ayers would have it for less money.
