Thank you! Still so much to learn....Two common vehicle-mounted radios during Vietnam were the RT-524 and the RT-246. They are very similar in size and appearance, the -524 has dial tuned frequencies, the -246 has push buttons for pre-selected frequencies. A lot of vehicles (for instance the V100) had a second receiver, the R-442, mounted next to the receive-transmit unit.
All three are pretty easy to find now, and if you are not wanting functioning ones, even easier.
Both big radios use the same mount. If someone doesn't chime in with the designation for the mount and antennae, I'll look those up when I get home this evening.
