  "limits": "Static raised-window construction, not an actual-car glazing survey. The80mm hidden extension/carrier drop is an unmeasured construction estimate, not factory glass height or verified window travel. Visible upper pane outlines, source lean,4mm lateral extrusion and main door/screen/body frames stay. Source main glass is still planar; handed fitted form, exact thickness and curved windshield geometry remain unresolved. Lower carrier/setting and roller centers follow the extended pane. Regulator mounting/winder/pivot stations stay; the guessed arms and lower return rebuild, and upper pins extend outboard to the relocated rollers. No original arm length is an owner measurement. Below the pane the front/rear guide has an explicit reference knee; it is not a compatible sliding-glass trajectory. All guide sections, depth, gauge, carrier form, roller/pin fit and mechanism proportions remain estimates. Factory p243 supplies glass/setting/channel/regulator roles and a467mm glazing-strip comparison, not fitted pane dimensions, a travel curve, arm lengths or hidden mounting coordinates. The source508mm carrier span stays; strip length does not measure that channel. Far/driver window state is unresolved; no lowered window is inferred from occlusion or absence. Both sides retain their prior raised reference state and assumed mirrored architecture. No body receiver holes, stops, impact-bar or latch positions are changed to manufacture fit. Fitted identities, compressed seals, meshing gears, working regulator motion, loads, actual clearance and verified replacement/removal paths remain unestablished."
