TR-85 can come in a few variants, some can sit higher (up to 10.0 in case of TR-85M1 imo due to a great shell, improved armor and thermals, plus good gun handling/ turret traverse and better RoF compared to predecessors).
Unlikely, Norway like us yanked the old connectors for certain weapon mounts for spare parts when it was interchangeable and given Penguin also mounts on the F16 and can be fired from the mount when the F-5s left service they likely took the connectors for spares.
We did the same to our F-35s and I know some Norwegian F-5s had them pulled
