Width of keeper. Sash lock mounting question.

Question

Hi,
What is the width of this keeper? I only have about 7/16". (I will try to add a couple pics). The sash frame is about 1-1/16. I would like to move the keeper out about 1/8", but I suppose I would have to remove 1/8 from the jamb stop for the 38-144 sash lock to line up.
Also, is the 38-144 made to be mounted to a flat surface? My Pella sash stop is not flat. Again, more modification. My Pella lock mechanism is behind the side sash stop and is jammed. Unusable. I do not see anything that is close to what my Pella window uses. Thought I'd just add a couple sash locks.

I'm not sure what to recommend based on your pictures. Seeing the frame alone doesn't tell us much, unfortunately. You could have one of the Pella locks like the 38-274 and 38-275. We also have the newer lock and handle kit 39-403 and 39-404. Take a look and see what you think. If not, we need to see the original hardware in order to identify a match. If your window has been modified heavily, there is a possibility none of these will work; Pella hardware is very particular, and only meant to work in very specific windows.
