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.

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.
Stringreen,
I did get the balanced box installed. The one they shipped me must be bigger than the one you have because it was too big to fit on the existing base. It was an easy matter to switch the whole thing out though. Once I got the top off, the screws to remove were right there. I wouldn't have gotten that far without your help though because I was stuck trying to figure out how to remove it from below. The box and anti cables only have a few hours on them but already sounded great this morning on Fragile, John Barleycorn Must Die and The Outlaws. Thanks again for your help. Without it I would have had to wait until Tuesday most likely after talking to VPI. You helped make my weekend a little more enjoyable.
Stringreen,
I agree that the balanced junction box was a worthwhile change and thanks again for your help with mounting it. One thing I think I have noticed is an increase in static charge on the LP after playing a side. I'm wondering if this is because the balanced box doesn't utilize a grounding wire as the single ended box did. Did you find it necessary to ground the box externally or should the ground in the balanced interconnect take care of this? This could also just be a coincidental finding as this is peak AC season here in Iowa.(This ain't no dry heat as in Arizona and the AC works it's butt off to get the house nice and dry which, in turn, may be causing the static)
I would also add that the balanced anti cables are performing quite satisfactorily in my opinion. It's nice to find an affordable product that works so well. Others will obviously disagree but it may be time to stand up say "The emperor has no clothes"(at least in reguard to certain high priced audiophile cables)
Thanks stringreen,

I don't notice any noise during playback either. When it's time to change sides, the disc is sometimes adherent to the platter with static which seems to be a new development. It's a minor problem. Just wondered if they were related.
