I do have some PDF files showing how to do the center section. The only change was opening up the tops of the forward crossmember in the center section. Also, for the Nitro version the deck separator for the rear hatch and front hatch has been moved back one frame. I will see if I can maybe even save those here as a jpg on the thread. Anthony is shipping the cowling plug today, and if I get it before the weekend, I will start making the mold over the weekend. Mike
