Part # KM50016898
It's a two man job, a lot of the times the frame to which the beam is fasten too is bolted at the bottom of the sill. So in that case you'll have to run the car down in the pit to your helper to Unbolt . Then run to the top floor and unbolt the top part of the frame. Change your sensors , use the original bolts that go through the sensor , cut old zipties back to the door board, replace and repeat .
Good luck
