Big Daddys 300

I am undertaking a project I know will be difficult. I have both auto and marine restoration experience. A 1967 Chrysler 300 convertible 440, 3sp auto, custom ordered car with some bells and whistles not found on many Chryslers. My biggest hurdle will be the uni-body frame repair. It is in poor shape but I believe restorable. This part of the project is where I will need the most advice. Any sound advice would be greatly appreciated.
