Steve,
Thanks so much for getting back. Unfortunately, I already did this, but used a position on layers 1 and 4 as I don’t want them to rotate, just come into the center. However, layers 2 and 3 overlap eachother as they rotate on their Y and its not the exact effect I want. I want it to be as if the center point between 2 and 3 is pulling them back and that point goes straight back and pulls 2 and 3 to rotate on their y and 2 and 3 in turn pull 1 and 4 to touch at their edges in the center.
Keying it by hand as you suggested gave a close result, but as I mentioned 2 and 3 overlap.
