I honestly do not know the brand on the ones on mine, I have never seen another set. They fit as if they were a factory option molded around the gas tank filler door and such. I think you are on the right track with CJ or YJ flares. I see a lot of guys running those because of the ease of mounting them and they can take a fair bit of abuse and stay on the truck. There is a guy that goes by "Biker" on here that could talk you through the mounting and which model to go after, or just start a new post and ask guys to show pics of what they have done. There are so many smart and helpful guys on here that are more than willing to help. As far as clearance, have you already trimmed the rear of the front well and taken a big hammer to the lip on the inside of the front well? That opens a fair bit of room up, enough to go to 235's without a lift.
