If you mean "crooked" or twisted chassis, there is an easy solution. Catch some hot water in something big enough to drown the chassis, after everything is off of it. press it flat, and when the resistance is getting slack, take it out and block it down flat on a surface to cool. Presto. Straight chassis.
