Stripped Retaining Screw on Ignition Coil. 1994 E320

[Johne 320]

Hello to all.

While replacing the spark plugs on my 1994 E320, I stripped the heads off of two of the coil retaining screws. These are the little head less screws that hold the coil in place. There is one screw per coil. The third screw came out fine.

1. Should I use a small "Easy Out" to get the screw out? What other method could I use?

2. Can I buy these screws at Fastlane or Partshop?

Thanks,
John
