Confused on Spring kit 68 dart

Your bottom spring does not look right to me but my cars are 70 to 72 maybe they changed something. My cars have a long spring going across the bottom, shoe to shoe the spring you have is going shoe to brake adjuster swivel . On my cars the swivel has an arm spring that keeps the tension on it, perhaps someone else can chime in on this. The swivel arm spring does not come in the spring kits
