When I had my 3 door Freelander back in 2001, I bought a parcel shelf secondhand and it did not come with the fittings.
I made up brackets to mount it - all you need it a flat steel plate, drill a couple of mounting holes then using a cut strip of steel, bend this into a U shape, lay it onto the flat plate and weld it in place, paint to match the colour of your trim then fix to the trim with self tappers.
Worked perfectly with mine
