What exactly is the problem? Is is that the allen head bolts that are behind the rotor that bolt the two chunks of aluminum for the upright together are loose? If so, can't you get to them with a cut down allen wrench? If not, what about just drilling through the back of the block and tapping the other section and then putting a bolt in from behind with some loctite? As mentioned, you should be able to adjust the front end with the control arms.

As for the previous style (like my car), it's the same thing, just with an original style upright instead of the billet. And the original uprights are weak loads of crap.
