I think i exceeded the heim joint angle when the tires stuffed, well it's obvious I did. The bolt was an f9 bolt and broke and didn't bend. Not sure a bend would have been any better as it was a clean break and after a cutting torch and some clean up it was a straight forward fix. I happened to buy some things in two's and had another F9 bolt for the track bar on-hand which came in handy.
Unbelievably, the track bar heim on the axle side was still good, as was the johnny joint and mount on the frame side. The misalignment spacers were also ok, but replaced them as a precaution.
I will of course be pulling the front end completely apart and inspecting everything and probably replace all the joints.
As Viper said, we made it to the finish line, this is a few miles before the finish.
