Hi, I am looking for some clarification on the torque specs for the front traction arm braces.

I took mine off to build my own power brace. During reinstall I was following my version of the FSM which shows 108-127 (80-90ftlbs) End up stripping the weld nut in the frame rail on my driver side, didn't get to tightening the other bolts.

Cut an access panel in the frame rail, drilled out weld nut and dropped in a grade 10 M10 bolt to replace the weld nut, started torquing a nut on from the opposite side to clamp the brace in place. Stripped the nut, started thinking is is a lot of torque for an M10. Looked up bolt torques and indeed saw that maximum torque for is 60-70 ftlbs, with grade 12 hardware.

Then found this thread where he is posting a picture from a fsm showing bolts are 39-49 which matches the sway bar bolts, but then his power brace comes showing the higher torque loads.

So what do you torque it down too? I'm pretty close to just welding this thing back on.
