I was using this on a Hustler MR41s with a flush rail type. I am selling it because I no longer need it after changing vehicles. Set Contents: XS400 Stay TR400 Hook XB100 Rear Bar XB108 Front Bar Hook Rubber Keys The rubber in the middle of the bar in the fifth photo is missing because I was using a different attachment previously, but it does not affect use. The included instruction manual and the manufacturer's dedicated hex wrench for tightening the hooks are not included, but you can tighten them without any problems using a commercially available hex wrench. Thank you for your consideration. #XS400 #TR144 #XB100 #XB108 #INNO
