Thanks for the warnings. The bars have been pretty well inspected, particularly in stress regions like the stem clamp, and don't show any signs of stress. The FSA bars are pretty damn overbuilt in the clamp area, and that seems to have helped. There is really a lot of material there, which makes me feel better.
Either way, these bars aren't going on a 'performance bike', just an around town bike, so they won't be used very agressively. I'll keep the inspections regular, as I do with all my 'salvage' gear.
Just be glad I abandoned my plan to repair the broken CF fork I found in the same dumpster.
peace,
