Demco #6099 Dodge Prep Truck Bracket installation

I can't speak for the Demco system but when I installed my B & W into the factory pucks the hitch base is equipped with adjustment bolts The instructions are to loosen the bolts slightly, enough to allow the "feet" of the hitch to move ever so slightly, the base drops into place, you re-tighten those bolts and from that point on you're all set. Might there be the same thing on your set up?
