what is the difference between the 90-005 and the 90-009? Our window locks have the name alenco on the top and our house was built in 1991 (texas).

The difference between 90-005 and 90-009 is the tongue. Take a look at this picture with 90-005 and 90-009 side by side. Also take a look at this discussion that includes more pictures of the 90-005.
