Ducana window replacement parts

I'm looking for both left and right casement lock keepers for my Ducana windows (built around 2003). The multi locking track utilizes 4 lock keepers. The keepers are missing so it's a crap shoot, but I would like to find something that may work.unfortunately the previous owner removed and three them away.

Some details that may help.
2003 casement windows for Ducana
The 2 arm crank mechanism is almade by Truth.
I have some numbers - locking handle and track.
The casement lock mount on the side of the window - screw holes - 1 inch apart.

It's 4 inches long and has a 7/8 inch height with the handle down. The handle and track are different. I included another picture. The arm from the handle to the track is 2 inches long. It's the side locks that attach to window I need ( missing). Ty.

I'm looking for the casement lock keeper that attaches to the window that moves in and out. The roller rack when moved up locks the window in place utilizing the casement lock keeper. I need four for a left and right hand opening window. Unfortunately they're missing so I don't have a picture.

I'm looking for casement lock keepers that mount on the side of the window. The ones posted look like they mount on the back side of window. I've included a couple pics of casement keepers that would work if they had more depth to allow engagement. It needs to have a depth of approx. 3/4 of an inch. The original keeper had screw holes with a one inch space - fyi (not critical).
