After consulting with Vans the aft bulkhead will be fine as long as there is no interference prohibiting the vertical stabilizer from mounting flush. The moment of truth came as a I temporarily mounted the vertical stabilizer.
SUCCESS!!
The vertical stabilizer mounted up just fine with no issues. For good measure I went ahead and stuck the horizontal stabilizer on and snapped a few pictures.
