I'm waiting for someone to try the SRT CV's and see what happens there.

If I was you dude, I'd take a piece of that casting that broke, call the manufacture (or NAPA to get the number) and call customer service. Send them that piece of casting that broke. Inform them about the weak housing. They should look into the problem and try to resolve it. Sometimes they may even send you a free CV or something.

At least thats what I do sometimes when we have quality issues where I work.
