Does the 550 K'nex piece tub have this piece: http://www.knex.com/building_toys/stard_black_rodconnector.php in it?
I want that piece badly because I want to make K'nex guns. Unfortunately, I don't have it. I am planning to buy the 550 piece K'nex tub and I think it has that piece, but I'm not sure whether it contains that piece or not because I do not want to spend money on a K'nex set that doesn't have what I'm looking for. And also, Does it also contain spacers and hinges?
