This is the stud that holds on the forward cam seal plates on 575 and 612. A couple of mine had the nylock nut stuck and the whole stud came out and when I removed the nut, the threads were stripped. Ferrari Italy has none with no ETA, and none in stock in US dealers. total length is 26 mm with external thread length of 13 mm and internal of 11 mm. I am considering 5mm threaded rod with socket head and using medium thread locker on it. http://www.mrmetric.com/M20465
thanks dave, yeah I have seen those. I looked everywhere. The short side is only 5 mm which is not much to grip into block insert or not much for the nylock nut to engage with.
also the length on long side of center must be 13 to engage the nylock and the others on the page have a center section too long and would not allow nylock to touch face of cover plate.
