True enough, but to do that, you have to know what the alloy is to begin with, and then know what level it's taken to - T-4, T-6, T-?? By the time it's welded, machined, heat treated and zyglo inspected, it'd be more economical to find a good intact used part.
If I owned the business, I wouldn't touch the repair with a ten foot pole, just for liability reasons. It's a critical part of the suspension.
