The two screws that hold the speed face on are not common sizes
They are between 4-40 and 6-32
It’s a 5-40 screw I think but I don’t recall exactly all I know is it’s the only location in the whole truck that uses that size
That includes screws in the radio like RF tuning coils and such
That odd ball screw is only in the Speedo face plate
