## Discrepancy

DURING WINDSHIELD REPLACEMENT IT WAS DISCOVERED THAT THE LOWER PILLAR TO CABIN CORNER FITTINGS PN 79553-800 ,-801 WERE SEVERELY CORRODED ALONG WITH SOME OF THE SURROUNDING ATTACHING STRUCTURE. THE FITTINGS WERE CORRODED SO BADLY THAT PITTING EXTENDED COMPLETELY THROUGH THE LEFT FITTING AND 90% OF THE RIGHT FITTING. THE ATTACHING BOLT HEADS ON THE RIGHT FITTING WERE DISINTEGRATED AND THE BOLT SHANK WAS COMPROMISED TO 60% OF ITS THICKNESS. THE RIGHT SIDE BOLT HEADS WERE CORRODED TO 60% OF THE ORIGINAL DIMENSION. PICTURES AVAILABLE ON REQUEST.
