Anderson casement window operator

A quick learner from USA says:

I have an Anderson casement window, I think it's built around 1996 or 1997 as one of the arm indicates.

I need to replace the operator. (See attached picture.)
The part numbers are these:
Front top: C-9400-1
Back top: C-9400-8
Arm: 2 361399, (or could be 2 1361399 as the First digit "1" is not very clear) 1/31/1996
I'd like to know if you carry the exact parts, or any parts that can be used as mine.
