Suspension fastener and shock problem

[LTRace]

More than likely, your lower clevis broke because your lower shock mount is sopposed to have 2 cup shaped washers that also act as spacers. I bet one or both are missing.

As far as the triple clamp bolts, they pretty much suck unless you apply anti-sieze compound to the bolts when they are new and then keep up on them. It seems the cad plating and bare cast aluminum love to become one. You need a savvy mechanic/machinist for the fix.
