The hinge is bonded to the sheet and the trim to avoid screw holes.
The removable trim at the front of the storage area needs to be removed and be cut to a straight edge to accept the hinge, simple enough.
Bonding the hinge to the trim creates the only datum for taking measurements for the sheet as the sides of the storage pocket are not straight and have also radiused corners. It took some time to get the fit correct.
If you have some patience and are fairly precise with hand tools and taking templates it’s straight forward.
