Window casement arm operators

A quick learner from Nevada City says:
I ordered some window casement arm operators from you. Parts 39-031, 39-032. I need many more to replace the old ones in my house. However, there is a problem. The old ones were from Truth. The arm with the moving part, has a linkage offset- going down instead of up. Do you have any with the offset going up?
Thank you in advance,

Hey, Michelle. I know what you're talking about. We don't have any operators with that same offset, but I think ours will still work for you.
