I would use bronze, rather than brass. Bronze screws are readily
available online. Plastic wall plugs should be OK if the stone is sound
enough to take the expansion force.

Ah - right. The instruction I have do mention bronze tools, etc. I'll
order up some bronze screws. They will go towards the centre of the block
which seems still sound.
