Yes, GM used ammeters in the trucks all the way up to 1975. Although the burnt wiring issues are more limited to these years because GM added some fuses to protect the circuit in the 1967 & newer trucks. There were a few years around 61/62 that used a fuse as well.
But for anyone who's keeping the stock ammeter, I highly recommend adding some fuses. Since it uses an external shunt wire to carry the majority of the current, there should only be about 2 amps (maximum) flowing through the meter itself and it's connecting wires. So the fuses can be relatively small (GM used 4 amp fuses in the 67-75 truck ammeter circuits).
