Need to replace 3 awning operators and need help in choosing the best of your offerings

A handy person from Pittsburgh, PA says:
The Left Hand Awning Operators I need to replace have no marking on them. I am attching a photo of the unit and listing below the dimensions:

The unit has two mounting holes top & bottom spaced at 5-5/16" center to center.
The top holes are 1/2" apart, center to center.
The bottom holes are 7/8" apart, again, center to center.
The swing arm on the unit is 3-3/16" long and has a 3/8" non threaded hole.
The holes on the arm are 2-11/16" apart.

I hope this is enough info to identify the best replacement unit. I saw that perhaps your, 39-279 , 39-079 or 39-017 might work, however, each one has one dimension problem or other.

I appreciate any help you can render.
Thank You,

Thanks for posting, George. Take a look at our 39-075 and 39-074 operators. I think their dimensions are closer to your sample, but see what you think.
