55.2-59 Hood rockets for 1957?????

I was talking to a friend of mine that has owned many 55-57 Chevy trucks over the past decades. I mentioned how the 57 has the bumps on the hood as the 57 Chevy car does except the car has the chrome rockets. He said they made some accessory ones for the truck. I've never seen that or heard of them, did they exist? Maybe from JC Whittney years ago?
