C-9400-1 Andersen Operator

A home owner from Massachusetts says:

We are looking for an Andersen EZ Split Arm Operator / mechanism for an Andersen window. The # on the front is C-9400-1 and the number on the back is F-9400-8. The distance between the (2) furthest holes is 4.5". I saw a recent post asking the identical question, but looking at the 39-264 operator and the 39-362 adapter plate I don't understand how this works for spacing holes of 4.5" when the same dimension on the 39-264 shows 3 11/16 hole to hole. Do new holes need to be drilled? Can the existing cover and crank be reused?

Thanks for your help.

I think you misunderstand the purpose of the 39-362 adapter plate. This is only used on windows made from 1995 to 1998. Andersen used a slightly different style operator on those windows that isn't a 1:1 replacement with the 39-264. The adapter plate simply allows you to use our part on that window. 

If your window is made any time after, then you can ignore the 39-362.
