My '72 half-ton six needs a heat riser. Anyone know where I can get the parts? I need the shaft, flapper, bi-metallic spring & counterweight. Sadly, many of the younger guys out there don't even know what a heat riser is. Here in New England, these engines run better in the cold weather if the heat riser is functioning properly.
I need one also! I am also looking for the pipe that connects to the air intake and the sheet metal piece that is mounted to the manifold.
