Slick Mag Harness Screws - part number/spec

[John Courte]

Does anyone have a part number or spec for the screws that hold the distributor cap onto the back of a Slick 4300 magneto?

In the clusterf-- er, process that was yesterday's magneto timing session, one of my screws fell out, and went missing, possibly kicked by yours truly or one of the other hangar occupants.

The problem with an asphalt floor is that you can't hear things hit it. This is how I locate most of the various things I drop, or used to before I moved to the airport. Small, non-shiny things falling on it might as well be sinking into the black depths of a Michigan lake.

Thanks in advance,
-John

Never mind. Part # M1553, available at ACS. Searching for "slick magneto harness screw" doesn't turn up anything, but searching for the part number does.
