It's tough to make a recommendation without seeing the whole operator, but start by looking at our 39-090 or 39-188. The difference between these two is the style of the gear arm; the 39-090 has a "Z" shaped arm while the 39-188 has a "W" shaped arm. You'll need to look over your original operators to confirm the better match.
