Hi there- thanks for posting! 

Could we see some photos of your operator? This will help us to determine exactly what replacement will work best for you. 

Thanks!

Thank you! This looks like an older operator. The closest matches we have are our 39-389 and 39-390, though I cannot confirm if either will work. Look them over and see what you think.
