Thanks for all the info. I tried everthing to open up the fulcrum balls, but no luck (just a bunch of burned drill bits) I have now pulled the big studs and replaced them with lt1 screw in studs. 7/16 bottom and 3/8 top. Will have to get new stock rockers now as I ground them out to fit the big studs. On the good side, I learned something, I guess that what happens when you like to play. Thanks again
