Siege/Earthrise Megatron arm adapter for ss86 Optimus Prime and any future repaints. simply unscrew the upper arm from Megatron and install the new part, then remove Optimus's arm via the mushroom peg and reinstall the new arm in its place.
EDIT: added v2 version. fit is a bit looser but allows the arm to be used on both ss86 optimus and earthrise megatron without having to remove the component and returning the original shoulder part.
