Anyone know what size/pitch the threads are for the 3 screws that hold the headlight retainer to the bucket?

For some reason I have 2 new retainers but only enough screws to work with one of them and I can not seem to determine what the pitch is of the screw threads. An 8-32 seems to want to start but not screw in as if it is the wrong pitch.
