Mine is a cross bread has all sorts of parts on it. I have the X bulkheads so when I go to different tracks makes changing fluid easier if need be. Yes my brace all so has some play in it. I all so will tell you that the upper arm pins on the X are known to come out around the poor stops on the bumpers. You can either use a zip tie to hold the bumper mounts together or do what I did. I do not like the way the zip ties look so I took a couple lower pins and cut them to length and use the old bumper mounts.
