I'd just go with an adjustable bar and not worry about it as well. I work at a shop and we do some lift kits and specialize in axles. While we wouldn't charge much, if anything, to look at it, I feel anything a shop would charge would be wasted as an adjustable bar is really the only reasonable fix. If the subframe is tweaked a bit it is likely not worth the trouble to fix that unless it's structural and needed anyway, in which case you could probably tell something's way off.
Yeah, tell me about it. I had it up on jackstands for a while, and I crawled around it and saw nothing obviously amiss. No obvious signs of frame damage or bent rails. I have a link to a bunch of pics somewhere else in this thread.
JKS makes one for 1-3". I've put about 35,000 miles on mine so far and its been problem free. Uses the same axle side bushing as the MOOG. You do have to drill out the frame side mount just barely to 9/16". Wear gloves and be careful because you're removing so little metal the drill will likely catch, but then you're done.
