NEW PRESSURE PLATE
If your pressure plate fits the Mangusta then why not just get it rebuilt? You can put a new disc with it or also have that resurfaced if a replacement disc is not available.
That way you know it will be work and it can be speced out to exactly fit the need of your application.
The clutch shop will know what you need based on engine power, torque, weight, car, etc.

I just got a message from Jack Dowling and he says he put a different clutch master cylinder from Summit with a bore diameter of 0.625" and it reduced the clutch effort by about 25%. I'll try that first. Changing the clutch is a big effort item for me. If that does not work then I get the old stock clutch rebuilt. Do you know of any shop that can rebuild a stock clutch?
I put the Clutch master from Summit and the clutch is noticeably softer and more easy to modulate. I can live with this clutch now.
