I’m not even sure if this can be done, but the Tamia kit seems to be a hodgepodge of the G1 and the G2 any expert advice would be welcome. Thank you Sean
Some of the notable differences on the G2; The hull-mounted tools are now stored on the rear right of the fighting compartment, and some on the engine deck. A stowage bin mounted on the rear right of the fighting compartment. The barrel cleaning container mounted cross-wise on the rear of the engine deck. These descriptions are a little vague without illustrations - maybe someone else can provide.
This can be a start: Jagdpanzer V Jagdpanther G2 (late production model)
If you can get Panzer Tracts 9-3, it should provide all the information you need:
