That front wall end does need to sit back behind the wall DeAgo gives us. Battery pack is in that area, hopefully there's room, looks like UK is getting that part this week.
Actually it does... the wall sits right in the middle of that area. The ribbed supports should go right against the wall itself. The large tube should be behind those supports which would put the tube BEHIND the wall itself. The problem of the battery pack however, that may or may not be much of a problem. If they intend to use the supplied battery pack, it should fit in nicely with alot of room to spare. If they plan to create a whole new battery compartment, then trimming might need to be done but it shouldn't be much of a problem.
