Not yet,I have been so busy with work and what not that I really dont get alot of time to work on the car.. 1 layed down 3 layers of dynamat on the whole interior section of the cars,spray foam in all cross members in the interior and just now started going back together with the interior..I have the birch cut but have not had the time to do the assembly of the box yet..Maybe this weekend Ill get a good start on it.. I decided to double wall the whole box with 3/4 11 layer birch.. I do know it will be sealed from the trunk facing forward and aero-ported through the rear deck..Ill post pics when completed.
