  "limits": "Optional factory comparison, hidden until explicitly selected. Owner exterior/bay/front-underbody images do not establish fitted horn identity, count, condition, terminal configuration or mounting pose. Factory203lists BHA5367high/BHA5368low fromGAN6-154101, with AHA6657RH/AHA6658LH twin-horn bracket roles; it does not locate them in this body frame. The shared illustration also shows earlier BHA4515/4514and37H7542/7543alternatives,57H5309flat bracket and two terminal cues. Its drawing does not certify the later horn exterior or terminal count. The MGOC mixed-family replacement page retains GGE101/102one-terminal andGGE103Z/104Ztwo-terminal labels; those labels do not resolve this fitted configuration. High is displayed at+X and low at-X only to distinguish comparisons, not establish handed installation. Both use identical estimated120mmcover envelope,18mmbody depth,estimated2\u20133mmsections,1.5mmfront face,6mmrim projection,100mmbracket rise/30mmfold offset,22mmwidth/2mmsection and9mmbores. Boss/stem,terminal block/post sizes,all centers [plus/minus170,550,1320]mm,axis+Z and bracket orientation are estimates. There is no acoustic diaphragm,coil,contacts,frequency,current,polarity,ground route,relay,wiring or operational circuit. The closed front cover is an outside boundary,not a demonstrated replaceable diaphragm. Bracket bores and smooth stem are recognition geometry,not fitted hole maps,thread,clamping,elasticity or loaded retention. No receiving body holes or backing are generated and no original part is moved,resized or drilled to make a join. Contacts and gaps are reconstruction results,not fitted interference,airflow/cooling performance,service access or safe replacement paths. No tightening,live electrical test,lifting/support or verified removal/refit procedure follows."
