Does anybody know the screw sizes for the 4-switch atari 2600 case? It looks like the rear ones may be a little bit longer. I have to get them at a hardware store so a callout would be helpful (ie: #4-40-3/4"). I tried a #8-32x3/4" but the diameter is to large. I bought this thing at a thrift store years ago and it never had screws, works great though. I want to put this thing together properly.
