Hey John,
I broke the spherical nut on my Cateks earlier this season. (see the thread"Catek users please read") I was going to invert the bolt and put nylock nut on top as you did but you need to hold the bolt from turning. Is that a allen socket machined in the end of the bolt? If so great idea. I was going to just grind the end of the bolt to put a wrench on it. any interest in machining a few bolts for me??
Joe
