Factory PDF137 illustrates alternative wheels, separate retaining nut and horn push. The drilled three-spoke topology is a catalog comparison, not a BHH1307 or actual-car identification. Rim major radius169.3333mm, section radius19.4733mm, center and plane retain the old viewer construction; these are not measured diameters. Hub35mm radius/40mm depth,14.3mm smooth bore,23mm counterbore,6mm web gauge,24mm web width,25mm dish,12 holes of11mm diameter, spoke clocking and blank cover are estimated. No splines, taper, projecting shaft, thread, nut size, brush/slip ring, horn wiring, material strength or actual horn function is invented. Existing shaft ends at the retained wheel datum; its engagement into the rearward dished hub is unresolved. Core/rim embedding is a static construction contact, not a manufacturing or loaded joint. Column, fascia, pedal and body frames stay. No steering sweep, ergonomics, tool access, safe release or verified replacement procedure.",
