As title says $20 shipped, it the plastic piece under the the air cleaner that goes over to your heat rise tube on your exhaust. Pix's later.
If this goes with the air cleaner you have listed, I may be interested in this as well. Same email for pic's please.
It will work on the air cleaner listed but the one you would need is like a rubber piece if memory service me correctly. This one is hard plastic, but will work either way just not original for 69'.
