I pulled the fuel tank access panels on my newly acquired 1977 M20J several months ago in order to track down and reseal a few small leaks. The leaks are sealed but the screws that secure the upper panels have gone missing. I have a supply of 10-32 100 degree countersunk 1/2 inch screws, but they appear to be just a touch long. I'm searching for the IPM to get a part number for the correct screws, or in lieu of that, does anyone know the correct screw (or even the grip length)?
Many thanks! I'm excited to get this project finished and back in the air.
