another quick thing I noticed is that modern lamp fixtures are designed for octagon electrical boxes in terms of the width of where the screws mount, and may not always fit rectangular boxes. If I were you, I would buy the lamp, check the 2 screws and see if they line up with the existing box in your wall, if so, go ahead and use it, if not, see if they come with brackets that adapt to the width of the boxes mounting screws. if not, looks like you have to go to rona or aikenheads and pick up the octagon boxes.
