Nippondenso Alternator

My 74 GT550 came with a Nippondenso alternator, after rebuilding the engine I finally get around to doing the electrics and find I have a major short which I track down to the alternator, the green wire has been attached straight onto the alternator with no insulating washers. My question is, what do they look like and can I get some from somewhere? Anyone have a photo of them so I can get some idea.

The parts diagrams doesn’t show it, but there is an insulator between the green wire connector & the washer.
There may also be an insulator separating the screw threads & the green wire connector, or it may be designed in a way that precludes contact between the threads & connector.

Not very clear, but parts detail here - https://alpha-sports.com/suzuki_parts.htm" onclick="window.open(this.href);return false; - pick year, model, denso alternator. I'll try and remember to get a pic of one when I go in the garage next time. I have probably got spares too.

I found an old petrol filter that seemed to have hard enough plastic and cut it down then used a Dremil to shape it, took about an hour during advert breaks while watching a movie. Worked perfectly.

Washer wouldn't work as it needed to be shaped to fit into the section.

Some plastic tubing that fitted inside some fibre washers would get you out of trouble.
