rear seat detached

ok, so i had my CD player installed at best buy. they apparently ripped my back seat out for some reason to mount my original deck in the trunk and run the wires back there. so my back seat is now detached from the clips that hold it down. does anyone know where i can find a diagram of the proper placement of the clips to get the seat back in place? the clips are these little black things and are oddly shaped and i cannot figure out how to fix it. going back to best buy and asking them about it is out of the question because of the long drive. any help would be appreciated. thanks.
