  "limits": "Owner IMG6329 supports a pointed amber front side marker with bright rim and lamp/reflex zones, not fitted hidden geometry. Both old marker centers and all neighboring body/lighting geometry stay. Moss2014p60 gives140x57x22mm L824 assembly bounds; Vintage Supplies gives approximately140x55mm and50mm two-stud centers. The2mm height discrepancy stays explicit; neither is an owner measurement. The model uses140x57 nominal major bounds with estimated internal sections and plinth depth. Integral raised reflex field extends0.7mm beyond the plain lens surface; lens screw/head, plinth and local tails lie outside the catalog body envelope. Factory215listsMidget AHA9338/9339plinths; Moss lists MGB AHH9964/9965. These are separate comparisons, not replacements proven interchangeable. Every outline, wall/gauge, bulb/holder station, screw/thread size, section, gasket thickness and unloaded sealing relationship is estimated. The50mm stud spacing is a supplier comparison only; one stud is near the bulb port as in supplier photos, not a fitted drilling map. Point-forward orientation follows the visible left marker; right mirroring is an unverified construction. No holes are cut in the wing and no surrounding part is moved. Gaps/contacts are source-registration discrepancies, not installed fit, tool/service clearance, loaded seals or a verified removal sequence. Bulb role GLB989 is factory-listed; fitted identity, voltage, wattage, holder contacts, polarity, ground and harness destinations remain unassigned. Smooth lens/reflex fields do not establish optics, illumination or compliance. Separate front side/flasher lamps remain absent and are a distinct incomplete assembly."
