Envelope follows existing unmeasured U-bolt axes plus10mm selected margin,not a scaled supplier dimension or drilling template. Supplier/factory topology supports one common part type in opposed orientations;generic mirror does not identify fitted plate,handing,press radii or collar machining. Existing spring-facing web planes,axle/spring/perch/pad/clip/bracket poses and feed pipe stay. No pad compression,collar/head seating,full clamping load path,material/strength,torque,axle alignment,loaded clearance or verified removal procedure/path. The fuel route is not an input to this reconstruction;any resulting separation is source geometry only."
