⚠️ CRITICAL VERIFICATION REQUIRED: Search results do not specify the bore diameter, engine model, or exact ISUZU NPR chassis/year range for this part. Additionally, the partial number “WC4283” appears in European catalogues as a VW application ( LW45511, 25.4mm bore, TEVES system). This may indicate a numbering conflict or cross-listing error.
