Opposite visor is an unverified mirrored construction. Smooth opaque mirror face has no reflection, prism/dipping optics or verified rearward field. No glare protection, visibility, compliance, breakaway/retention strength, pivot/sweep, hood/door clearance or verified installation/removal procedure. Source gaps/positive contacts remain reconstruction discrepancies; existing door mirrors remain their separate coarse browser comparisons."
