South Bend DXD Kevlar/metalic 6 puck clutch.... Tried, tested, abused
"The DXD SS Puck kit contains a extreme clamp load pressure plate, and a 6 button, true dual friction clutch disc. By using ceramic buttons on the flywheel side of the disc and 100% Kevlar® buttons on the pressure plate, this disc will provide all the holding power required by today's serious racers. "

IIRC it was about £550 from Horsepower Freaks. But the exchange rate is much better now!
You're welcome for a test drive if you're passing
