From the way Kahuna worded the question, it almost sounds like the racks are missing? The Ironman came with the racks, but since it was bought second-hand, someone may have taken them off. If so, you get the racks from an Isuzu Dealer or better yet, from Merlin at St Charles Isuzu (free shipping plus a web discount).

I just recently bought BigMike's load warrior and extension, but I haven't mounted it yet.
