Owner6789/6853/6856supports installed pin/spring/front-panel context, not fitted part identity, dimensions, catch engagement or a complete cable trace. 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."
