I made these for my Frontier, but have now sold the truck. They attach to the Utilitrack system. Thread where I showed them being made: http://www.clubfrontier.org/forums/f10/ammo-can-storage-182073/ The finish is a little worn, but they worked great!! Ammo cans NOT included! Hardware to attach to truck included. $150/obo, for the pair or $75 each. I prefer not to ship these, as it may be expensive, but I could look into it.
