I have used something similar. If all plates look the same,not for K6 and later.
All 8 plates of same model despite my K6-76 must have the outer disk with wider ears. I broke the outer disk twice (2 kits) until I understood that the clutch kit did not match my clutch. K6-76 and later have the outer disk with wider ears.
If not, the ears of the outer disk will have a huge play and it will crack the plate.
I have now std like clutch (cheap from cruzinimage) with Barnett springs
