You are looking at hard to find Lionel parts that you do not often find for separate sale. THIS LISTING IS FOR one set of BLACK molded & WHITE MOLDED cowboys (total of four heads) that rest on the pivot arm and appear to bob in and out of the window.
This may be just the part you need to complete that cool sheriff car--or you can turn any bobbing horse car into a sheriff car as well.
These are the parts that go in the stock car that Lionel originally released with cowboys bobbing out the sides, #9305.
