Hi there, Mike.

This should be something we can help with. I'd just like to see a bird's eye view of the entire operator, including the arms, all in one shot. That will help narrow down some options.

Here are some pics of the operators and arms. Hopefully this helps.

Thanks for getting back to us! Our 39-028E or 39-255E operators look like a modern version of your old assembly. Look over the dimensions and see if one matches up. For the opposite-handed version, see the 39-027E or 39-254E.
