Buying a used AutoTemp II Servo is a waste of time and money. Sorry to be so blunt, but that's just the way it is.
The servo unit has the misfortune to live right next to the passenger side exhaust manifold. Extreme heat and plastic don't work well together. Many of these units cracked in less than a year when the cars were new. There is no fix for a cracked servo--one might be able to seal up the crack on the outside, but there will still be coolant leaking into the electrical components on the inside. Liquid coolant and the electrical/vacuum innards of the servo unit don't work well together either.
Information about the aluminum bodied replacement servo unit (which is a *permanent* fix) is available on our club's website! For each of the three relevant years (1971, 1972, and 1973), it's listed under the "Repair Literature" section. For example, have a look at 1971 at http://www.imperialclub.com/Yr/1971/index.htm
Yep, it's expensive! But it works! And, really, it's not all the expensive comparatively . . . the last time I bought an NOS power servo unit from Chrysler was in 1987 (before I knew about this replacement), and it cost just over $400 then.
And yes, that NOS unit cracked in less than two years.
But once you throw the money at the aluminum replacement, you can comfortably forget about any further worries with it.
Good luck!
Elijah
