I have changed the board, transponder and everything, but when the time comes to change the blade I was surprised because the slot is smaller and I cannot put my original blade into the metal hinge, which let me to reuse my old hinge+blade. Also one suggestion from my side: It would be good if you include to the package also the locking pin for the blade.
Original blade does not fit into the slot on the replacement hinge. I do not recommend this product if you are looking for complete assembly refurbishment.
