If there's any way you can give us an idea if these parts are replaceable we would certainly appreciate it very much.
The best we can come up with in measurements is that it's 3-5/16" long x 3/4" thick at the latch end and approximately 5/8" high. The 5/8" is based on the space available in the frame not an actual measure of the part.
There are no visible markings or stampings on the windows or the frames.

Thank you so much for your help!
Sincerely, Trudy
I've attached photos of them in the window:
