-dark blue arches and pillars
-correct white panels 1x2x3
-dark bley birds
-possibly the dark red roof bricks, but someone said they made more
I would try to get as many parts from PaB as you can, as they are generally cheaper than Bricklink, and you are paying a low shipping cost. As others have said on Bricklink, create a wanted list by doing a set search by cataloging the set number, and going through the inventory. Then go to your wanted list, search "by shop", and you will see shops that have what you want, allowing you to order from as few shops as possible, keeping shipping costs down. Once you figure out a lot of the nuances of Bricklink, it is very handy, with tons of info.
Wow - the dark bley birds sure got pricy on bricklink! Just a few weeks ago I found them for .45 ea....I should have bought more!
