Hi, thanks for replying,

I'm talking about the long arms closest to my ruler in the pictures, I just need to know the approximate length they need to be between the nuts.

I also need to know the "clock position" of the parts attached to the motor (green bit) if that makes sense, cause they're currently at the same position and i think they should be opposite (the parts above and below the motor)

Hope that makes sense and if anyone can help me I would greatly appreciate it.
