November 17, 2009 - Thanks to Brandon, the brackets are welded on the top of the diff.
I ran the torch, heating the whole area up to about 700F. Once the heat had stabilized, Brandon stick-welded the brackets on with a nickel rod as I continued to play the torch around and keep things warm. Once the welding was done, I continued to heat the differential and gradually brought the heat down. Once we got it down to about 450F, we wrapped the whole thing in a welding blanket and let it cool gradually overnight. The end result? No cracks!
Brandon would probably like me to mention that it's a bit out of practice, but the welds are strong. I tested them by beating on them with a hammer.
