I used a 3 inch kit from a 91 ranger short box and had 2 left over, as for bolts good luck with that I made my own by threading the ends of some rod and machining a head on the other end, but that was because it would have taken me to long to have bought the right length and have them shipped and i had access to the rod and machines. if you look up the explorer performance acc. body lift kit I think you can find a parts list with the bolt lenghts and quantitys, just make sure they are for the right size body lift, then you can order from about anywhere you can buy a quality bolt
