This incident damaged the threads on inner pressure plate.
Spare parts are very cold today.

I would like to have a stronger inner plate with thicker towers for the 4 bolts.
I have a billet part with the bearing.

I'm not sure this applies here.  :-\
The bikes which have 6mm hold-down bolts for the clutch springs;the 6mm bolts are light,spinning weight. I had a bike which had 6 clutch springs and the spring towers were thick,so I drilled-out the holes for 8mm bolts for the springs,but that might not have been best,considering the centrifugal weight of them?
