I see what you're talking about....

I was able to get mine quite a bit more parallel than yours - still have a bit of a bow - but that's because it's not all the way parallel - keep in mind, as my truck has sat in the garage, slowly adding more weight to the frame, it has leveled out by about a 1/4"

^^^ shows how close to parallel I got with the lower arms - this is now a little closer because of motor and cab weight, but still needs to be redone! All this was done with a spring compressor which is now unbelievably bent.
