Hello,

Take a look at our 39-279 and 39-280 ad see how the dimensions match up to your original hardware. Thank you!

The link arm on my existing operator from pics above measures approx 1.75" from center of bushing to center of hole. Will a 1.5" link arm work?

Hey there! I think it'll be fine. There is a lot of play in the linkage for operators like this. You can definitely get away with a different in size.
