B&O Beosound 9000 floor stand! Bits missing?

[mikeb]

I have bought a floor stand off ebay but cannot seem to fit it (the 9000) to the backing plate.

I have four black screws with x4 plastic bobbins and the stand and backing plate. Is there something missing? The backing plate has milled out slots in the aluminium but I don't seem to have anything that slots into them.

Anybody got any pics?
