Keith - I guess your best solution is to call Unique. I had the same dilemma during my cooling system assembly. I bought the hoses as called for in the Unique Assembly and spent a lot of time looking and twisting and trying to figure out what went where.
After talking to Maurice or Alan, we realized that there was two parts I was missing(they shipped it the same day). One was a piece of connector pipe that fit on the other end of the raditor hose coming from the block. This pipe ran through a hole in the bottom front cross member in front of the engine. The other end of this connector pipe connected to a second "L" shaped radiator hose and then to the lower radiator inlet connection.
Mine is a Windsor so might be different, I just feel that you may be missing a connector pipe to make the deal work. Mine did look like a big "S" and the other a big "L" before I did a little bit of trimming to fit. Hope this helps - good luck - send more pics.
