Ive done a few things to this affect... the rack is Tractor Mikes "Tractor Caddy" the rest of the gismo's are from Northern Too. The little Orange metal tool box I got off of Amazon or Ebay iirc and bolted right up to the existing brackets behind the tool box with already drilled holes in it. Its the "wrong" Orange but it sure fits nice and easy. Holds a lot of various types of spare pins, Fuses, a couple of adjust able wrenches, a 4 in one screw driver, little pry bar, a big plastic hammer, Rag, Gloves, a roll of wire... and other things I cannot right off recall... such things for field repair etc.
