Thanks for your post! Our 90-323 Sash Lock and Keeper Set may possibly work as a suitable replacement for your repairs. Another option is the 90-252 Latch Mechanism used with the 90-252 Latch Cover. 

You'll need to remove the existing latch and compare the dimensions shown on the website to determine which of these might be the best option. 

Carefully review them and feel free to reach out with any questions!
