Help identify window crank

I believe it's a DYAD , 39-089/39-090 OR 39-187/39-188

I am not sure the difference when it says SASH DYAD or when it says Window DYAD.

Also the length of the rod is 4.5" as opposed to 5", not sure if that matters.

Hope you can help, can't open either bay vinyl window because both cranks are not working correctly, it's soooo hot in my house.
