Where do the pieces numbered 4255629 go in the Death Star (set 10188) I just finished up the Death Star set, and while it comes with the usual smattering of leftover pieces, I've got two pieces numbered 4255629 (shown below) that never got used.  I've scanned the manual three times now and just can't see where I missed the pieces.  

Were they just included for decorating at my leisure, or is there a specific page that shows where to use them?

The piece looks like this:
There is one going in the small blue trolley on page 4. These pages don't show parts inventories, and the part is partly hidden, so it's very easy to overlook.

The other one is an extra, as explained in comment.
