Well the area where the torsion bar section and frame rail intersect is completly gone in my case, also has holes in that rail too, the drive side is good but with out a passenger side what is it worth? Nothing in my opinon. Rear frame rails have a dozen holes in them due to the salt eating away at it. Re caping or double walling the frame is only nessicary (SP) if you are putting a powerful engine in it that can twist the chassis.
