Certainly possible BUT expensive. Everything about radio costs money. Groan, says my old lady.
You can own every radio in the world but you only need a Ham Licence when and if you TRANSMIT.
That's not to say you can't know your gear actually works. ha.
In that period was basically all American. Most all in the range was part of the VRC12 system.
Plenty info on Mr Floogle. Look for AN/PRC77, GRC/160, RT524, AM2060 Amplifier,
RAA (Arty) RAAC and RASIGS. Anything up to four or more even.
Two mounting holes ?? Don't drill any more till you get the gear.
Start trolling ebay (Europe, Italy, Israel and the USA) USA won't export a lot.
Do some research to get up to speed on what's needed. Start small (even just one set)
Send me a PM for further questions when you think of them.
Work on getting the vehicle fully kitted then start on the radio gear.
I did it back to front. See ya,
