KM773390G04 is a parallel elevator, and it requires 2 boards of the same version to be used. Buy 2 pieces at the same time and use it together. If you only buy 1 piece, you must send the original piece back to adjust the version to be the same (there is no extra charge for this). G05 is a single ladder, there is no version problem like G04.
