I bought a glue-in windshield for my ’62 Jetfire restoration project from Pilkington and they had a different listing for the glue-in and the gasket. The ’63 is the same windshield as the ’62. I pulled my invoice from Pilkington and they have it listed as a ’63 with part number DW00623 GS3. Their books may not go back to ’62 or they don’t have a correct listing for ’62. ’63 is the same situation as ’62 and the windshields are the same. Hope this helps.
