If you have power brakes, it looks like you're missing the lever and push-rod assembly. These pieces bolt in between those two big braces under the dash and are extremely awkward to get in or out (unless I don't know how to do it the right way). My only experience has been with power brakes so I can't say what you need for standard brakes. I wonder if a lot of these pieces are shared by other Mopars--Chryco could tell you.
