Aint that the truth.
If it was an offroad Dart I would feel different about it. :-)
Seems to me about 2 inches either way from center is about the average on the travel.
Don't know about your car but mine has a two peice hub, so I can separate them, pull the clip for the torsion bar, take the nut off the front of the stabilizer bar and slide the whole thing back enough to replace the lower control arm bushing and/or the stabilizer bushings.
(LCA bushings are poly also, so I don't have to mess with sleeve pressing)
Takes me about 30 min a side.
