Kawasaki KZ650 B from 1977, a chain guard (chain guard)

Good afternoon, I am looking for my Kawasaki KZ650 B from 1977, a chain guard (chain guard) identical to the original, in plastic, REFERENCE  36014-068  , could you help me and tell me where I could find it? Thank you greetings.

I do not think there is anyone making this part any more, but did find this site that appears to have it in stock. Please note I said it appears to have it in stock.  I do not know if they do or not.

If they do not then I would suggest looking at ebay or any bike junk yard for one. 

Says not in stock at the moment but will be in a couple of weeks knowing zpower.
