This kit includes all the parts needed to retrofit the third magnet to a Twilight Zone pinall machine. A precision template eliminates the guesswork in drilling the playfield and the ball guides. A special opto receiver eliminates the need for complex add-on boards. You will also need the magnet coil; magnet bracket; pole piece; nut. You may also need the home ROM. The ROM and nut are available from me, and the pole piece, bracket and coil from suppliers such as Bay Area Amusements.

You should consider ordering the nut also.
