All sections,spring wire/turn counts,pin/undercut profiles,catch keyhole,hook curve,pivot map,plate gauges,route smoothing and mounting shapes are construction estimates. Main axis,carried heights,body/catch planes and cable route stations retain existing drawing datums. The safety pair moves from reflected browserX=-84.6667 to the existing native slotX=+84.6667mm;this is a source-coordinate correction,not actual-car handedness evidence. The pin plate has a6.8mm radius internal comparison bore;independent bonnet/body receivers stay unchanged. Spring end anchors remain unregistered. No fitted fastener map,thread,lock state,adjustment,preload,spring force,cable tension or hidden attachment is inferred. Cable sheath/ends are hollow comparisons;inner-wire routing,remote clamp,clips and body crossing remain untraced. Bonnet-carried groups follow the existing illustrative four-bar pose;body lock/bracket/cable stay fixed. This does not establish catch release,secondary-hook operation,collision clearance,safe support,service order or verified replacement/removal."
