After 834 plays and second time travelling to Planet X.

Now to set my sights to 2 billion

Hello fellow pinheads, alas, my Mechagodzilla has literally spat the magnet out of his chest. After disassembly it seems the central screw holding the magnet in place inside the coil has disappeared.

I have thoroughly checked inside the cabinet and playfield and I cannot locate. Please help me identify what size screw I need and also a washer assuming?
