  "limits": "Optional comparison only: owner6329/6341do not expose the boot interior or identify a fitted spare. It is hidden until explicitly selected and is not a verified installed obstacle. Factory301lists five roadwheels, five tyre valves, four Midget hubcaps in the disc-wheel branch and four Rostyle trims; no road-wheel cap/bright trim is duplicated onto the spare. AHA9881Rostyle/AHA9940clamp, disc24A1032and wireAHA6664clamp branches remain documentary alternatives, not fitted identity. Existing 4.5JSLx13bead boundary and145SR13designation are factory references from the wheel source; tyre outer radius, aspect/profile, uninflated/loaded behavior, tread and all formed-wheel sections remain its estimates. Rim/tyre reuse exact native prototypes and mesh topology at a rigid90degree rotation, with no rescaling. Horizontal pose uses the boot drawing midpoint inZ and low-floorYplus half nominal designation width; this is an independent construction, not a recovered stowage position. It is not moved/tilted to hide floor/ramp/filler/body conflicts. Clamp wing100x22mm,3mmsection, stemR4.8x116mm and height are estimates; stem has no thread and no engagement/retention is verified. ManufacturerAHA5741boss is a separate catalog role, without a located fitted boss or generated receiver. No floor hole, boss, tank alteration, body movement, cap/trim or unverified valve seating is invented. Positive contacts/gaps reveal source conflicts, not actual-car fit, storage capacity, loaded restraint, access or removal clearance. No tyre/wheel recommendation, inflation pressure, tightening torque, jack/support procedure or verified spare removal/replacement method follows."
