Window crank and latch

Hello,

I'd suggest starting by comparing the specifications of the 39-031 Entrygard operator to yours. This is used with the 39-107FK handle and cover kit. 

Dimensions for 39-031

As for the lock, I can't be sure without seeing the lock fully removed from the window, but the 38-036 would be a good place to start. Take a look and see how they compare. Thanks for posting!
