No strength, body alignment, door operating fit, pedal travel, wiring/pipe clearance or verified cutting/welding/removal procedure. All body sections stay fixed during inspection separation. The left front/top body now includes a rearward mounting platform projected from the existing pedal body gasket, with an estimated step and side returns to the old roof. The old roof is opened beneath the projected central mouth. All8 reference bores share the unmeasured base map.
