I am looking for 3 assemblies that go on right lower corner and two that will mount on the left as seen in the picture.

Thank you for submitting your photos to us. In your case, I believe you may be able to use our 39-258 and 39-259 window cranks as replacements. Look them both over and let us know if you agree.
