Hey there! I believe it is the 39-147 right hand operator (out side looking in). Remove the plastic cover off of your existing operator to see it the gear location matches up to the 39-147 dimensions. There also might be a "R" stamped on the operator arm which could be a tell this is what you need. However it is best to remove the operator completely from your window to be sure.
