68 Spoiler to valance screws

[68rsssrag]

What are the correct type of screws to use for factory correct finish on the 1968 optional front spoiler. The ASM I have does not include a page on D80 so I have no part number and no details as to head or lenght. Anyone have an old parts book with this detail?

Thanks
