in the end up using needle nosed pliers and removing both the plus sign notches from thee space bar, used a toothpick to lift the metal stabalizer at a 45 - 60 degree angle and slotted the support mounts back into the small notch
Works pretty well now I believe . Can't say if its good as new but registers each press and doesn't wobble ( Audibly louder but seems to be quite common for the space bar )
Pretty poor design Though , was hard work releasing the two side mounts with pliers , Can't imagine in this instance the removal of the spacebar could do anything bar loosen them from the stabalizers .
