I fixed the aux tank mount problem by drilling the nut plates, elongating the holes for the bolts then drilling and countersinking new holes for the nutplates. Problem solved. With the tanks mounted next was riveting the top skin on. Luckily for me my mother and step father were in town for the holidays so I put them to work. It took us about two days but we finished the left wing and moved it over to the rack.
I also started putting the rear fuselage together which went a lot quicker than expected once the ribs were all built. Currently I am only able to install the lower aft fuselage skins because sling sent me the parachute version and I ordered the non-parachute.
