Intairco makes a laser cut nose former kit that extends a tray into the nose cone, with pre-cut/drilled holes for a PowerBox Royal. I used that. You can see pics of it in the FB build photos by Intairco, I dealt with them (Peter Agnew I think?) directly through FaceBook Messenger to order the parts. They also make an aluminum pitot that threads into an insert in the front of the former.
