LUK for sure, that's what I swapped my clutch disc out for. basically anything that doesn't have the same hub design as the one pictured.
It's hard to see, but some of the springs were actually rubbing on the flywheel.

Below you can see the gap between the hub and the disc. None of the springs are broken that I can see, and I had a terrible bounce on accel. Problem solved with a new disc.

I'm still trying to find a part number for an SMF LUK Conversion.
