Cracked diff case

[Lawrence]

If you're handy with a welder degrease and wire brush the area then grind I shiny at the very end of the cracks drill them out with a 4mm drill then blaze it up no worries

Thanks for the reply guys. The welding option seems like the best bet as any GU diffs would be extremely rare here. I am checking out the option of getting a used GQ diff as well. Can it be welded on the car?
