I agree, the 39-188 and 39-187 look close, though it's hard to tell if your arm is offset or if that's just the glare on the metal. Can you confirm?

If it's just glare, then I think those two are the way to go. You can simply swap the link arm from your operator with ours. You can drill out the rivets to remove them and then pop them back on with our 62-014. Could that work for you?
A home owner from N Syracuse New York says:
After reviewing, my husband thinks this will work for us
if he swaps the link arms I will order the needed parts, thanks for your assistance, much appreciated!

Thank you! I haven't been able to find a version of this operator with an offset. Can you tell me if the offset is down or up? Could you also take a closer picture of the arm, from the side, so we can see exactly how the offset looks? Thank you!

Thank you for your patience in this matter. I'm afraid I have not been able to find a version of this operator with that offset. I see similar parts, but they've all been different. I'm not sure if this is available anymore. The only thing I can think of is trying to retrofit our 39-187 by maybe adjusting the bracket. I cannot guarantee that this will work, though. I am sorry we cannot be of more help.
