56 instrument cluster module holes?

[56sedandelivery]

So have this instrument cluster module that has 5 small hole drilled in it. This is the way I got it but been too long to remember if there was something there or not. Anyone have any idea what these holes are for?


Also anyone know the size of screws that hold the instrument cluster 10848 to the panel 10838? Tried 8/32 but that is not it. I did get metric 4mm to work but did not know they used metric screws back then.
