I have a cl350 that the PO stripped out the Phillips head of the screws for the small engine inspection cover on the right side of the motor. This is the small round cover that is held on with three screws near the rear brake pedal. Which Phillips bit fits these screws the best? I use to have a small hammer impact that would fit these but it went missing. I think the Japanese Phillips is a little different size. Does anyone have any suggestions on how to get them out? Does anyone know where you can still get a good hammer impact that will fit these screws? Thanks
