VPI balanced junction box installation


I was wondering if anyone has installed a balanced junction box on a VPI arm. I have the 10.5i and just got the new box in the mail. I can tell there are two screws/bolts holding the single ended box on but the holes are so deep I can't see what they are without turning it upside down. I'm trying to do this without moving the table (SSM) because I've got it leveled already and just kissing my rim drive. Can anyone tell me what type of tool I need to get the single ended box off? I could call VPI of course but they're not open on weekends and this is when I have the time...maybe.

The box is a bit tricky. It doesn't look like it does this, but the metal is actually U-shapped. You can get this off by removing the 2 chrome Phillips head screws. The whole box does not get removed...only the U-shaped metal that contains the jacks which goes around the top and then down in front. Remove this piece of metal with a screw driver...just pry it up in the back, and slide it off of the top. You don't have to take the piece off that says VPI. Take the similar piece off of the new box - I suppose it now has the XLR connections on it, and simply slide it on to the existing connected piece of box that is already installed on the table. Replace those 2 chrome-like Phillips head screws (unless you are going to use the anti-skate device) and you're in business.
I just read my post above, and let me clarify further that these are the chrome screws that are on the very top of the box.
Thanks for the help. I would never have figured that out. It certainly seemed like it needed to be removed en block from the bottom. With any luck I'll be running balanced in the morning. I'm trying the anti cables with it.
