Yeah I've still got the speakers and parcel shelf.
I made it, the base is MDF and the spacers are made from layers of marine ply glued together. Its not the sexiest looking thing youve seen, but with a bit of carpet over it, it would come up a treat, I just never got round to it. And it works, which is the main point of having it in the first place.
