Ignition Parts

Finally getting everything bolted back together on the 81 kz1000, and it turns out things go missing when you leave a bike in a thousand parts for over a year. The ignition coils on my bike use those screw on caps to secure the wires in place, and 2 of them are missing. Does anybody know where I can get some replacements or alternatives? Thanks in advance.

There is a guy on ebay right now parting out most of a kz1000 1980 i think, he may have them, he has everything else it seems. His ebay handle is: drewsracing
