Reply to "clutch disk"

I just replaced my disc with a JEGS 049055-107 10.5" 1 1/16" 10 spline for $86.99.
this went under a center force Diaphram pressure plate, typically a mustang size clutch.
I used a sanding disc to rough up the pressure plate as a quick fix. 30lb dual pattern flywheel.

I will be going back to the 11" clutch with the new motor to handle the HP. I like Hayes!
