If I might assist....
Top image: The big set on the left mounted on the radio shelf is an AN/GRC-106 (ie RT-662/GRC plus AM-3349/GRC-106, mounting MT-3140/GRC-106, and (not visible) antenna group AN/GRA-50 or the whip antenna: three of MS-116A, and one of MS-117A and base AB-652/GR). The AN/GRC-106 is an HF, SSB. There is an C-2328/GRA-39 local control set sitting on the shelf to the left. On the shelf in the middle of the vehicle at the front is an AN/VRC-46 (RT-524 and MT-1029/VRC, and (not visible) Antenna AT-1729/VRC) , with what looks like an AN/PRC-77 (or AN/PRC-25 - they look the same, and both were still on issue during the period in question. The '77' is a more modern updated set) sitting on top of it.
Lower image: The AN/VRC-46 and AN/PRC-77 are again visible in the middle of the image, and to the right of that is another AN/GRC-106. The stack of radios equipment to the right of that appears to be the two major components of the Radio Set Control Group AN/GRA-39, the remote control unit on the top (C-2329/GRA-39) and the local control unit (C-2328/GRA-39) underneath. The radio under that appears to be an Australian PRC-F1 (this is the manpack set: as a ground station, the basic component becomes a PRC-F2 when equipped with the conversion kit MK-F7, or a vehicle station when it has the installation kit MK-F8), and at the bottom of the heap, well ....?
The speakers visible are Loudspeaker LS-166/U (or 'Loudspeaker, Dynamic, LS-166/U'), and the handsets are H-33/PT.
The Aust gear (PRC-F1 etc) might prove to be the most difficult. Active collectors will have a better idea of availability than I do.
However, the above may assist you in looking for the right 'gear' if you intend to replicate something like what is in the image.
