Yeah. F' racing Planet. They suck monkey nutz.
There are no fly springs made for OEM clutches except for some that might fit, and I don't know what they might be. Contras will all fit except for the Malossi Yellow. There is one that I ordered from Malossi direct in Italy but it was years ago, and I forget the number.
Your best bet is to return that stuff, and throw a few more $$$ in to buy a Proper clutch, and some springs.
Deal w/ Louie at SPI and pay like 40% off the retail price. You can get a whole Polini kit for under 70 bucks including rollers.
I spent about 20 minuites looking up the stuff you got, and didn't even find the numbers on RP USA. That's why I asked Which country.
