i was looking for a orange one when i found this one. the base of the jack sits on the carrier and has a bolt to hold it and then close to the top there is a bolt that goes through the holes in the middle of the jack with a tab and a nut. the bumper and carrier is made by garvin really great to deal with. when i got the jeep someone at the dealership helped themselves to the tire mount. so i called them and they sold me just the mount, got it in a week!
