Hinges to go with pellows sash crank operator

A contractor from Lowell Massachusetts says:
I have a customer with 6 pella windows and she needs all new hardware Hinges and the sash operators. The sash crank operators are part # 39-175 and 39-176. The arm connecting the hinge is 11". Do you guys have those or can I make the 10" or 12" ones work

Dave Sr. from SWISCO responded:
I would double check your arm length. I'm not sure that Pella carried odd sized hinges like this. They all seem to run on the even inch. If it is 11", it may be an older type no longer made.
