Was finally able to get the underfloor opened up, and fixed. The cross member in question only served to allow a place to bundle some wires to, and to screw the plastic underfloor to. Put an new self taping screw in to hold it to the frame. Also found that the cross member to the rear of it, was never attached to the frame at all, the flat tab on the end of the cross member did not have a hole in it, and was not attached at the factory. Put a self tapper in that one too, before I buttoned it back up.
Thank you all for the input on this.
