Hi all. This has probably been addressed but I cant find it. I have a 2013 wrangler sport. I need to remove all or part of the front stock bumper to install some tow bar attachments.i need to know if the black plastic part separates from the steel part or do they come off together.I ask because i have some physical limits and don't want to get in a pickle I can't handle. I will be fabricating my own attachments for a used all terrain tow bar I got at a real bargain. Any insight on this will be much appreciated. Thanks pat.
