* Change {1 to 2} Part Black bb704 Technic, Link Tread Attachment, Single, Rubber (Extra)
Comments from Submitter:
I'm 100% sure that this set contains 64+2 pieces of bb704 as I've just recently opened it. One of the big sealed polybags contains 64 pieces of 57518 dbg link treads and a smaller polybag with 66 pieces of bb704 black rubber attachment, so extra part count for this item is 2 instead of 1!
