2WD Allignment problem

[stinky]

Here is my problem: My front tires wear in the following pattern: The left tire has the inside thread gone and the right tire the outside thread gone. To me it sounds like both cambers are set to the right. Air pressure is OK. The ball joints on the right were replaced about a year ago when it had an allignment done. I am getting an allignment done by a different place next week but would like to hear of maybe things other people experienced with these trucks.
Also, I think my truck has different front coil springs. It sits unusually high in the front for a 2 WD, it is basically level, none of the typical sagging. I don't know if there is such thing as a leveling kit for those like they exist for newer trucks. I was wondering if that could influence my allignment, but even if it did, it shouldn't cause the wear pattern I have.

Any inputs are welcome.
