:confused: Are the front bumper bolt patterns the same for a CJ, YJ and TJ? wondering if a CJ or YJ after market bumper will fit my TJ

I have a bumper that was designed for a YJ on the front of my TJ. If I remember correctly,all I had to do was enlarge one of the top holes(on the bumper) a little to get it to fit.

YJ and TJ are really close, like a 1/2" one is 30.5 and one is 31, or some shiat. CJ's are narrower by a couple of inches. 27.5 I think
