I have a 1992 chevy silverado. 4.3 V6. The clutch fork is okay, I went to replace the clutch, pressure plate and throw out bearing. When I went to remove the locking tang on the stud that acts as the pivot for the fork, the tang was brittle and broke into pieces. I went to every part store in town and none of them carry it nor can get it anymore, they all say it was discontinued. So what options do I have now? Can I just drill it and slide a kotter pin in it`s place? use a dye to thread it and use a nut? Run out of options here and don`t know which way else to turn. Any advice highly appreciated.
