Going to replace the passenger side rear level sensor. Does anyone know what size the Allen bolts are that hold the sensor on? There are 2 of them. They look like 4 or 5mm.

I just changed mine and it is still showing fault.....the joys of used parts. I have it in front of me now and I just took off the single nut holding the bracket as it was easier. That will leave the 10mm nut/or is it 8mm on the arm.
