GD ROM mounting screws

[OldFoo]

Well, I be lacking a GDROM bracket, so I want to cobble something together. Anyone know what kind of screws (thread count, length, or whatever distinguishes screws) are used to mount it onto the bracket?

If I remember correctly, they are the same type of screws that hold Naomi carts together.

Thanks!
