Call Swag offroad, Troy is good people, I met him out west a while back.
if you have a YJ, you could also just get a CJ tail gate, drill some holes for the hinges and be done. you will have to make up some type of backing plate though.
I have a swag offroad tailgate kit, I like it. I is simple to install, but you have to paint or have everything powdered first. Great little project...
