Sadly not. But you might find the cause of the previous breakage is the cable adjustment. If it mechanism hits the end stops on the gearbox end before the pedal contacts the stops at the front you can find that the pedal is pushed hard enough to break it.
You are right badget, the diagram (from 900e manual) shows the arm in board, whereas see pic, the spare assembly I have shows it outboard.... Is yours a 900t/e or 850? Could they be different? I haven't actually checked the assembly on my van.
