Cranky window crank and lock mechanism

The window crank gear is stripped and the locking mechanism won't catch on the keeper. Does this crank assembly need the adapter mentioned in the description?
The glass area of this window is 31.5 x 43".

I forgot to add: What is the correct crank assembly and adapter if needed shown here? What are the proper locking mechanism parts that need to be replaced?

Hello, thank you for posting! 

Your crank operator resembles our 39-264 . The 39-362 adapter plate will be needed if your window units were manufactured between 1995 and 1998. Regarding your lock, please start by viewing our 39-290 and 39-291 . Please let me know if you have any questions.
