If the part is discontinued bike bandit will not do you anygood. The part may still appear on their website but when you try to order it you will get a email back stating that such and such part has been discontinued.
If the manufactor stopped making it, then you will have to go used and search salvage yards for it. Do a websearch for motorcycle salvage yards and then your search can begin.
I work on classic old bikes when I have time, and many times the parts are just not available so it is swap meets, salvage yards etc. You could try joining a group like vintage japanese motorcycle club.org and seeing if any of their members have any new old stock or decent used parts to sell you.
