Where are all the running hot posts?

It's a factory AC car with the factory system but 134a.

If I don't shut off the AC before it gets to 210 it will overheat.

I can't imagine everyone with an AC car in 1973 doing that.

Of course I could name some of the obvious like maybe a bad thermostat or a partially clogged radiator or I've even pulled a water pump apart and only two of the eight fins we're still operable and the other six flaps had broken off...
