Need to find a large plastic project box

[GusRobin]

In the mods I am doing, I need to find a large plastic project box. I need something that is about 8" inches square. I tried radio shack and the bet they have is 8" x 6" X 3". So far the only other thing I have found is plastic electrical junction boxes. Anyone have a lead as to where I can gfind one (looking for one that is opaque)
thanks
