The idea behind this part came after trying to re-install the doors on my 2007 Jeep Wrangler JK. The door is heavy and typically takes me a couple tries to align the hinges. Top and bottom. This part will act as a backstop for the hinges on the door. The front can be used to place your trail badges, stickers, or team logos. There is a LH and RH version. And to install, just remove the doors and slide onto the Jeep hinges.
