More pics. The sticks need to be cleaned and one microswitch on one stick is missing the little extended metal piece that goes above the actual switch button (may be able to put one on there or just a new switch). Otherwise they seem ok. I do not have the game board, so I haven't tested them myself. The guy who had the game said it worked fine.
You can (hopefully) see in these pics that they are wired opposite on the optical boards. One from at the top, one at the bottom.
