While waiting on EIB, I received a package today - Kev's inner drop boxes! Kevin is nice enough to pre-scribe the line needed on the outside of the inner boxes, which made me realize my outer boxes were the wrong size (per http://www.whitearmor.net/forum/topic/30142-drop-box-placement/) - mine are nearly 18mm. So, another item to change, but it will be worth it on the road to Centurion.
