I have a '91 YJ 4 cylinder and it did not come with power steering from the factory. I looked at my friends '95 YJ with a 4 cylinder and I have all of the brackets necessary under the hood to support power steering. I did not know what kind of steering box I could use that would be the most cost efective way. I am in the Southern California area and I did not know if used parts would be an option, and if so any leads on a place to get them in the area would be appreciated. If anyone has done a similar type of setup any information would help.
