'82 1000 Katana turn signals source?

[motolist]

My first post!

I have a recently acquired '82 Katana 1000. It has some goofy faux carbon fiber turn signals. I'm looking for original pieces. Anyone know where I can get them? I've been watching Ebay for months, but nothing has turned up. Bikebandit wants $53 each for new. Over $200 for all 4 is kinda pricey. Are these interchangeable with other Suzuki models so I can look on Ebay searching for different models?

not sure but maybe ask these guys, if you haven't already.
