Any idea what I'm missing with the R-915 rudder stiffener positioning on my RV-9? The holes in the stiffeners only line up on the skin if I position it the "Wrong" way.
Vans note in DW-7 (photo attached) says to trim excess material from the front side of the piece. When I clecco in the stiffeners, the holes only line up if I have the excess on the aft side of the piece.
R-915 pieces don't appear to fit differently whether I'm using the left or right half the the pieces that were separated.
See attached images of the positioning on the right skin - both the wrong way (by my reading of the instructions) and the way that seems to fit.

- Image 1 - DWG-7 note
- Image 2 - all excess is aft on the right skin - holes line up
- Image 3 - excess is on the front side - zoom in and see holes to not line up
- Image 4 - excess is on the aft side - zoom in and holes line up
