certainteed tilt window parts

I got parts a couple of years ago for my windows, I think they were window pivot bars #26-353. Can you tell me if the tilt latches 26-288 and 26-289 will work for the same window? Also, along the side of the window is a vertical slot that the pivot bar rides in and the tilt latch locks into, at the top of that slot is (for lack of the exact terminology)a "stop" that snaps into that slot and keeps the lower sash from being pushed all the way to the top of the window opening. I don't see that part in your literature. Finally, which vent lock should work with the window described above?

Thanks, they look like the correct parts, but I was wondering if the "26" at the beginning of the part # indicates they are all for one particular window or if that is just a general#? Also, any idea about the part I had mentioned that stops the lower sash a little short of the top when opened fully?
