Builder Note: When installing  the ribs in front of the four fuel tank ribs add the spacer plates in the photo in Step: 05B on the back side of the spar.  
 
Step 05B: Install the spacer plates at the front of the four fuel tank ribs. These four ribs are not trimmed at the front. this is not per van's instructions.

Builder Note: I left the flanges on to help with the loads from the fuel tank. This requires longer rivets.

Builder Note: Install in reverse order will make the riveting easer.
