I am about to install the wings on my G-200 kit and noticed I am missing some parts referred to SB #6. I should be able to make this parts somehow.

Looking at DJ's plane's pictures I noticed there are two triangular flanges sitting on top of the wing spar carrytrough that are not mentioned anywhere on my manuals. 

Does anyone have some referance on them? Or at least does anyone have some informations like dimentions, layups and core material?

I will try to upload a picture taken from DJ's web site so to understand what I'm talking about and SB #6.
