A c-clamp... another thing I need to keep in my tool roll LOL
Guys, this is *NOT* the front, it's the rear, a failure that occurred in 2005, which I repaired myself with a mig welder. Something similar happened in the front now... but I haven't seen it since I had it flatbedded over to the frame shop, and I'm not sure exactly what the new break looks like.
CobraED, I welded a triangular support underneath each side of the bracket as you said. Fix is solid so far. Flex is obviously the enemy. As you can see from the pics, there was some rust in the crack, so it happened over time.
