I may be late to the game here, but I have the same pulley/damper assembly as does Peter. If you need them, the part number for the cam sensor is 1F1Z-6B288-BA. It is NOT Motorcraft DU-57 (Ford F58Z-12A112-AA). The crank sensor is 1L2Z-6C351-AA. Just for grins, the synchronizer is F7TZ-12A362-AC (Motorcraft DA-2097).
