71 duster manual steering

Hello everyone I have a 1971 duster roller that I bought a couple months ago the previous owner was in the process of switching over from ps to manual I believe most of it is there but I am not certain I believe he told me everything is there except the idler arm? I am not sure if that's the right name or part just what I believe he said he mention something about the one that's one there no is facing the wrong direction? I'm not sure but was wondering if anyone can help me out with getting the right part or part number for what I am needing so I can put the steering back together and get ready to drop a engine into it thank you for any and every response
