Thanks for reaching out to us. This looks like an older version of the 39-035. The 39-036 is the opposite-handed version. However, the link arm is 3-15/16" when measured as shown below. 

What you could do is swap out the link arm between yours and the new operator. You can do so by drilling them out and then installing the old link arm on our operator using the 62-014 rivet. This would need to be hammered into shape.
