This is a new very high quality and correct reproduction anti-squeak kit. This was originally made for the CJ2A and CJ3A but works great with the other under the seat fuel tanks in the Willys jeeps. This felt set is located between the fuel tank and body. It keeps the tank from rubbing the floor pan. We all know how pricey a fuel tank is. This will keep the tank from rubbing a hole in itself from the friction of metal on metal.
