Truth operator hardware

A quick learner from Belle Mead, NJ says:
I'm looking to replace these operators. They seem to be about 12.5 inches from the rotating disk at the end until the bend in the arm. These are two separate operators. Both say Truth on them. Do you know what parts they would be?

I think you might have an older version of our 39-013 and 39-014. Look these two parts over and let me know if you agree, or if you had any questions!
