2 sets of windows need replacement openers

A quick learner from Santa Fe says:
Hi. I have 2 70" tall x 27" wide casement windows with operators like the first 2 pics and then 2 that are 31" r tall by 16" wide and their operators are like the second 2 pics. Can you tell me which operators to order? I need a L/R pair for each set of windows. Thanks VERY much!

Hello, thank you for posting,

Please start by reviewing the style and dimensions of the 39-031 and 39-031 operators to see how they compare to your original. 

For the second operator shown, please review the 39-035 and 39-036 style to see how they compare. If new covers and handles are needed, take a look at the 39-107 and 39-114L. Let us know if you have any additional questions!
