I'm real sorry but what is an OBA kit??? Is that the thing on the front of your Bronco?
OBA = On Board Air. It's that hose you see hanging out of his grill. He's got a compressor and tank so you can air up tires and run impact tools on the trail. It's a very valuable modification. The thing on the front of Dave's bronco is his winch mount. Due to the size of the Warn 8274 winch, he had to fab up something that would keep it up and out of the way so as not to ruin his approach angle. He kindly refers to it as the "winch stinger."
