Power Steering fluid change

So- I'm changing out all the fluids on the '72. The next chore is to suck out the fluid out of the power steering pump. I remember back then, we used that red Dexron automatic transmission fluid to top off GM cars when they were low. That's all good but what do we use as these fluids have changed over the years to meet new car's needs?

The owner's manual for my 70 calls for power steering fluid or ATF. The only improvements that have come along in power steering fluid is the availability of synthetic fluid. ATF is much the same. Synthetics are an improvement over the old stuff. Synthetic ATF is easier to find than synthetic power steering fluid, so I use synthetic ATF.
Regular power steering fluid turns to sludge when cold. ATF doesn't, so your hoses and fittings last longer with ATF.
