The flanges of the crossmember were rusty, so we have removed the outer sections and will replace them. Rust where they meet the inner sill will require a patch there as well, but that will allow us just enough space to slip a subframe tube into here. We have also removed the slightly rusty, but VERY dented footwells, and the rusty lower section of the inner sill. Typically, I would probably replace the inner sills on this shell as well, but in this case we are trying to salvage the factory seams for a virgin look on the interior of the finished project – as this car will have no interior carpeting, etc. Our patches will be virtually seamless, and reinforced by more subframe tubes in the sills.
