Hello, Greg: wow, a 37-675 is a swell set and well worth doing right. Color me envious!
Since you have been doing this awhile I will refrain from the basics, which I am sure that you already know. What I will say is to be VERY CAREFUL when getting into the RF deck. The components there are difficult if not impossible to get to without some major de-soldering of other components that are in the way. As you know, the old wiring in these sets is not good about being disturbed, so you may end up with a major re-wiring project here. I have discovered that the electrolytic capacitor mounted on the RF deck can be tough, the one on my 37-670 had 3 values contained in it, so that is 3 modern caps that you must find room for. IF you do decide to do some "major surgery" here, I would consider replacing the RF deck's rubber bushings, as they are often pretty worn.
The rest of the 37-__ radios are pretty much straightforward.
