I noticed that the USMC Cougars with the DUKE antennas don't have the top rear rectangular section mounted as in the Panda kit with the Chamelion. The ones with the DUKE have one large box on the top left rear of the roof and a smaller box on the top right rear with the LED light bar. Does anyone know what those boxes are? Are they part of the DUKE system? Also, does anyone make those in aftermarket parts? I did a search and even on Shapeways and couldn't find anything similar. Thanks for any help you could provide.
This is the version I would like to do.

This is the Panda kit version with the top rear rectangular section mounted.

Here is the rear showing the different boxes mounted.

Here is another rear view showing the different boxes mounted.
