Some additional pictures of the pipe tunnel.

Canopy deck. Make sure you allow 1/8 inch overlap for the two 3/8 inch side stringers. I glued the bottom 3/8 inch side stringers on, placed the canopy on the airplane, then glued the front three bulkhead/formers in place. I used a clothespin to clamp to the front fuselage bulkhead. Next is to mount the ply mounting tabs (its easier to get to them before sheeting the top of the canopy deck).
