Like finding a needle in a haystack but Mongo was right Airtech had the molds a few years ago when I need some. R6 stuff works well too. You might try getting hold of Steve at Speedwerks. He seems to hoard FZR400 stuff and might have an old set laying around.
Here are a couple I have done. Sharkskinz, Airtech, Beasley all still have the oem stuff too as far as I know
