WOW!! what a blunder with a great follow up recovery!! I commend you for hacking up the ribs like that. I'm not sure i could have ever done that without losing my mind! When i glued in the I-strut brace things, i quintuple checked everything to make sure as i didn't want to be left in a pickle.

As far as the dihedral, i put a 1-3/16" block under each wing tip. For some reason that made me feel more "balanced" if you know what i'm getting at. When gluing, i put a weight on each wing tip as well as a weight in the center of the wing. I haven't gone back to check the dihedral for certain, but it seems ok. I have to go check the i-struts as that will be the "end all be all" as the whether the angle is correct or not.
