AD stands for Advance Design, which is the model name Chevrolet applied to the '47 - '55 1st trucks. GMC used New Design.

Stovebolt was an early name for the Chevrolet six cylinder motors and has long been applied to the vehicles that carried those motors. Here the definition is a little broader and welcomes pretty much all GM trucks up through 1972.
