Quoted from DaMoib:There are two small pegs and one large peg on the cam. Match the wiper small holes to the small pegs. The reel has the same hole pattern as the wiper. Just line up the two small holes of the reel with the small holes on the wiper and pegs. [quoted image]
I coulda sworn that those old reels had that diff pegs but I haven't had one of those era games for a long time, and in the first pic up there the pegs all sorta looked the same size.
