Side extensions fill the previously open floor-to-quarter strip and meet the central low floor at its existing edge; the outer lip follows the existing quarter interior construction. This is not a surveyed seam, flange/weld map, normal material gauge, continuous load-path or repair template. No tank or support is resized/shifted to erase conflicts. No new tank stud holes, sender hatch, spare-wheel mounting, drains, rib stampings, axle clearance or rear-wheelhouse closure is inferred. Existing ELC neck/floor and tank/support conflicts remain open. No measured body registration, corrosion/repair assessment, loaded support, strength, safe release order, cutting/welding or verified replacement/removal path. These welded panels stay fixed during inspection separation.",
