if anyone can help me with this I would appreciate it. put new fredette chain guide on, 2 bolts go all the way through the swingarm, 1 small bolt goes into a heli-coil in the back but I pulled it out by apparantly over tightening it. looking at it, is there any option to replacing the heli-coil ? I would hate to do the work and have it pull out again. apparantly these are used as threads in soft aluminum to give the bolt something to screw into and hold under torque. thanks.
