I have an 89 Canadian Targa Supra, and well u know how most Canadian cars age over time! PART of the frame rails are rusted, but not completely rotted. Being that the chassis is based upon a unibody construction, structural points are integrated into every part of the chassis including the BODY. Do you guys think that the REAR most part of the frame rails serve more structural support opposed to the ROCKERS, which are pretty damn beefy or do you think the rails are. The frame rails are pretty light gauged steel compared to the metal throughout the rockers. What are you all opinions. Being that I absolutely hate the sight of rust and I'm a wiz with metal( Welding/sculpting) I want to replace the rusty part of the rails. Tell me what u all think!
