Here’s a clearer photo to illustrate what I’m planning and the reasoning behind it. The red line represents the new frame rail, which will be relocated to align flush with what was originally the inner edge of the factory rail. This shift will bring the rear frame rails perfectly in line with the front rails, allowing for a straight and structurally sound path for the subframe connectors.
The connectors will run from the leaf spring boxes, through the new rails, and into the original torsion bar crossmember. From there, 1" outriggers will tie them into the rockers for additional support.
Out back, the rear rails will be bobbed at the wheel well opening. A boxed section will extend from there to the quarter panel extensions. The new rails will be butted against the inside edge of the old ones and welded together, with the tops boxed in to maximize strength. The green in the photo indicates where the boxing and reinforcement will be added.
Hopefully this makes the layout and structure a bit clearer.
