I'm having trouble with my bobtach left side where it is attached to the boom it keeps losing up and when i try to tighten it the bolt just spins not like its stripped, threads are good its like whatever the bolt goes into is just spinning, i got the bolts back out of left and right side of the bobtach and i cant get it off to see whats in there am i missing something here looks like there is some kind of bearing in-between the boom and bobtach it looks bad allot of play only on the left side, can someone help me get to the bottom of this thanks Joe
