Face Mount Keeper and Window Lock

A home owner from San Diego says:
I was looking at replacing the 20 year old window hardware. What's visible on the pictures is all I got. I don't see any markings and I also don't see any brand identification on my windows that could give a clue. San Diego tract home built in 2002 if that helps narrow down the product.
I compared with the specs of the 90-257 keeper and the 90-077A window lock which I ordered. From the measurements it is very close. But these parts don't work. The lock mechanism is just slightly different dimensions.
On the keeper pictures my old part is on the right and the 90-257 on the left. Window lock pictures show the old part on the left and the 90-257A on the right.
Let me know if you have any parts that might be compatible.

Hello,

We'd be happy to help but you mentioned that your dimensions were slightly different than ours. We would need you to write out your exact dimensions compared to the images below to determine if we carry anything closer that might work for your repair. The distance between the installation holes is especially important. Thank you.
