Hey mate I don’t have the part number as it was already on the Jeep when I got it. I’m pretty sure if you can find a Chrysler or Jeep wrecker in your area they would have one. Other than that you could try a company in America called Quadratech…or Morris' 4x4 they may sell them
It looks like this at bottom it
it helps
