Bottom slide-in T Pivot Bar

I would like to know what is the correct part number to the bottom Slide In T-Pivot Bar for the same window

I saw your reply, I think that part is smaller by half inch. but at the same time that was the only part that i found on your website unless the information on the website its incorrect as far as the measurements
