He will probably need a copy of "The Red Book" or "The Yellow Book" to get it going. People who were into converting old tube-type Motorola gear back in the 60's - 70's to the ham bands will know what those two books were.
However, the "G" series receiver wasn't a good Repeater receiver even when it was new, and was never intended by Motorola to be used in Repeater service. It was much smaller than the "A" series receiver, and was intended for Base Station and Mobile only use - not as a Repeater receiver. The Sensicon "A" receiver is the one he wants if he really wants to have an old Motorola Tube-type repeater. We converted lots of those to 2-Meters in past lives. I think I heard that Motorola still made a few of them as late as about 1964.

By the model numbers you gave, I seriously doubt the FCC will allow those radios on any commercial 2-way radio frequency. If going into the amateur radio band, you will need to adjust the transmitter deviation to conform with your local area band plan ... usually meaning +/- 4.5 kHz Deviation ... clearly not a hi-fi sound.
