8 3/4 housing brace and perch welding choices

Those real long welds that go the full distance are the ones that warp a tube. The end welds are doing all the work anyway. A bracket that goes further around the housing will take less weld. I use my air hose after each short pass to cool it down. Water in a spray gun works too. Lotsa air; little moisture that dries on contact. With the axles out and some third member parts out of the carrier, you can look thru a housing and tell if it's warped.
