ACT is aware of the issue and has changed all of the rivets from hollow to solid on the new pressure plates. I did not ask how far back this was changed.
ACT also has a higher quality clutch disc that ACT now manufactures.. my old clutch disc was from Exedy that was branded with ACT. They are now producing a high performance clutch disc.
Everything seems to be sorted out now, it looks like some of the older units *may* be faulty.. but ACT is willing to address the issue and make the customer happy!!
