Probably the biggest area of concern was the rear chassis leg and shock mount area. Where the chassis legs overlapped had excessively rusted at the seam and had rusted through to the floor. The repairs might not look factory but they're solid . The bottom of the shock mount had rusted. It was a pain to remove and to repair. After being welding , I checked with the R/H side and its practically dead on . Apologies for all the photos.
