As to stripping, I used a heat gun and a putty knife for stuff I removed. Tedious and time consuming--particularly the undercoat if that was applied. Maybe others have a better idea.

Packard used what they called an "asphaltic based material" to help deaden the sheetmetal drumming. If in several -maybe a half dozen- smallish patches strategically placed, believe that's what you are speaking of. There are also patches in the doors and roof. If it is widespread then probably something a previous owner has installed.

To replace, some of the modern acoustic materials such as Dynamat or similar would probably work better anyway. If you are going to add AC then maybe some of the combo heat and sound materials. Doubt you will find any custom made kits like those for more popular cars such as Quietride makes but Summit, Jegs and others sell universal cut to size sheets. For sound, doesn't need to be wall to wall. Most of the Dynamat pieces are relatively small (and expensive). If for combo sound and insulation, then those sheets are fairly large and also expensive. Several have used modern foil type insulation available at the home center with good results--but doesn't do much for sound.
