Shoe liner material is what has changed. I have replaced drums (front & back) on several older vehicles and never had squealing problems.

They can be better described as harmonic dampeners. Drums and rotors on the lathe have to be wrapped with thick rubber straps for the same reason. Will sing like a bell if turned while naked.

Here are the drums I got from NAPA for my '69 c10. Nearly identical to the original units. Guess one could try transferring the springs over if so inclined.
