Pilkington Classics (I think they are in Ohio, or maybe Illinois) supplies correct windshields for these cars with the LOF logos and date codes. They know the difference between the glue in and gasket windshields and carry both. Not cheap, but definitely correct.
I understand that all F-85 (Cutlass, Jetfire, F-85) windshields are the same. In other words, there is not a different windshield for a Jetfire as opposed to a standard F-85 or Cutlass like Jim said.
