My QB was a 7, but I am pretty sure they use the same wings. If so, there are no pre-punched holes for the wiring conduit. This is one area, where Vans could save us all a ton of work. Looking a builders logs, nearly all of us end up drulling holes for conduit. Punching one 3/4" inch hole in the correct location would probaly add less than $1 per rib, but save the builder (espically the QB builder a ton of time).
Ok - down from my soapbox. What I did was to make a plywood template that I could slip into the wing thru the access holes with a 1/4" hole in it at the correct location. That way I could drill the wiring conduit hole in the same location in each rib. From there, its just a bunch of 12" drill extensions and step drills.
Hope this helps,
Jason
