CPS2 screws

Does anyone happen to know the size (width/length) of the four Torx screws that normally hold the 'B' board (ROM board) PCB into its case?

I have one minus all the screws you see - not worried about replacing them with torx, any screw will do as long as it fits, just not sure of the size/type.

Thanks

I would just take one to the hardware store so you can get the right size and pitch.
