Hi All,
Due to no incoming Euro-mail not sure if this will be seen but here goes. 
I recently did the lay-up for the NACA inlet for the cold air induction on 
the classic cowl. Along with the kit I received a 5"x8" piece of 3mm ply. 
It's too short to be cut and used for the skirt down to the airbox; the hole 
in the airbox being slightly wider. What is this ply for? There is no mention 
of this in the instructions that I can see. Did I miss something?
Thanks,
