Need additional measurement of the 39-069

A quick learner says:
I would like to order two lever awning window operators, 20-1/2", by Truth Hardware, on your website the part number is: 39-069. On the Truth Hardware website there are specific measurements which I can't find on yours, thus I can't be sure if I'm getting the right part, they need to match existing operators in my home. On the Truth website there is a diagram of the operator with several measurements, the one that concerns me is the one pertaining to "Y", and the measurement I'd like is 2.218" or "F" on the chart for Escutcheon Plate. I've pasted the link below.

thank you,
