Rear/front wall projected-Z thickness retains the existing viewer offset, not a measured wall gauge. Lip depth21.1667mm is inherited; rear18mm and bulkhead20mm upper returns are estimates, not factory flange dimensions or welded ownership. Rear wall side edges now follow the common side-camber function to meet quarter construction rather than retaining the old constant top width. No new lamp receivers, body holes, sender hatch, hidden reinforcement, drain/seam detail or actual repair condition is fabricated. Existing quarters, lid, hood, lamps, filler, tank, wheelhouses and body supports keep their source poses. Shared boundary contacts/overlaps do not verify welds, strength, support, sealing, fitted clearance or a removal path. Native seal compression, hinge/closure operation, bracing and replacement/cut/weld procedures remain unverified; inspection separation is illustrative.",
