Offset gear in operator

Home Owner from Fresh Meadows, NY
I purchased 39-005 which is the wrong size. Also, my old crank has an offset (it is bent, I figure that is an offset?)in the gear, do you think that is important? Can I just use another model? The other problem I have is the arm, it is only 2 12/16 Please advise me.
I am sending you 3 pix so you can see my problem and HELP me. Thank you.

Good morning! Thanks for posting. Before I can recommend an applicable replacement for this operator, can you first give me its inner and outer hole spacing, center-to-center? Thanks!

The operator's (gear?) Inner center to center hole spacing is 2, outer seems to be also 2. Since I can not detach the operator and there is an offset that is my best measurement.

The arm's hole to hole is 2-3/4

"The outer holes are 4-3/4 apart Inner are 3-7/8 apart

I seems that the offset is important because when I place both operators -mine and yours- flat on a table, the gear and arm of mmine rest on the table while your 39-005 both pieces are up 1/2" in the air

I don't believe the bend in the gear arm should matter. We do have a few offset operators, but the offset is in the link arm. I don't believe I have ever seen an operator like this and I don't know if it is available. Do you know the manufacturer of the window? Are there any markings or stamps?
