With a some clutches you get a realease plate without punched nibs.
Certainly some of the Sachs 'Sporting' Clutches have this release plate
SO this does not happen.
(Release plate from my PB clutch was after just 190,000 miles. Mind you it was a LUK unit?)
As it was scrap, I practiced my welding on the back of the pip.
I contacted Sachs but they were unhelpful.
