Window Sash Lock replacement

Thanks for reaching out to us. I'm not certain that we sell this exact lock. We sell a couple different parts with a 1-1/4" hole spacing, but I'm also concerned about the backset. 

Right now our best option might be the 90-180, which has a hole backset of 3/8". You can see its dimensions below. Can you verify this same measurement on your own lock?

It should also be noted that the 90-180 is currently only made in white.
