This was the right part for my dryer.  It came with the thermostat and thermal cutoff.  The thermal cutoff was proven bad by testing the part with a voltage meter and not getting continuity through the part.  I went ahead and replaced the thermostat also since it was provided.  My dryer is back to running properly.  The clip on the thermostat was just a bit tough to get off and I recommend pulling the whole heater enclosure out to work on it.
