We do carry Fenestra operators with 9" arms, but they're a somewhat different style compared to yours. See our 39-344 and 39-358 and let me know what you think. These operators have both mounting holes for installing on the sill, or mounting holes that go into the lower rail of the window itself. You most likely have a window track like the 39-504 in which the end bearing of the operator arm rides. If you operator will not slide out of the track, it could be damaged. You should be able to unscrew your existing track if you need to.
