Looking to buy or trade 2 blue base plates (48x48)

[TheRebricker]

I'm pulling together a MOC for but don't want to have to buy 2 Sydney Opera Houses to get these two plates:
ElementID: 6030733


If anyone has 2 in relatively good condition I'd be willing to buy them, or trade depending on what you are looking for. Send me a PM.

I also have a list of additional stuff, but figured I'd rather not pay shipping for at least these two parts.

I found two of these years ago at toys r us for my drawbridge. Have you tried there?

Wait. Those are the larger 48x48 baseplates, aren't they. Never mind.

I have not but certainly will! Thanks! They are also on bricks and pieces for $25 each.
