both myself and now my brother suffer from the issue of wishbone bolts that just spin and spin What do the bolts screw home into? is it a captive nut hidden away in the leg or a threaded section in there? Meaning we have both done a small amount of cross threading?
pretty sure its captive nuts..you may need some of these http://www.ezlok.com/InsertsMetal/index.html
