front lower control arm thread stripped, helicoil advice??

[ricktb]

I changed the front lower control arm, and the 2 bolts were rusted pretty bad.. One snapped off but the other came out easy, but I wasn't able to torque this one to spec. Should I attempt a helicoil? Not sure if theres enough metal in the spot, but I would think so being a main support point. Would a helicoil hold as well, being it only has 13 threads at best, compared to the 23 threads on the 12mm bolt. any advice would be helpful thanks.
