peterbilt one window door conversion

can anyone chime in pls
i wanted to do it for a long time and today i finally disassembled driver door
i didn't convert it to the electric , decided to keep air lines i have .
i removed wing window (i think its right word for it) with some damage because i didn't know its attached to the frame with 2 screws - not a big deal
the aluminum track thats ligned up with wing window (main window slides in and out in it) - how to attach it to the frame so new one piece window slide in it and doesn't fall down .......
also after installing new one piece window i have small open hole in the corner where wing window been ....on newer trucks there is metal piece covering it ()not sure if it can be ordered or its part of newer door frame
kinda disappointed
have window installed but can't use it .... i can probably put tape temporarily to cover the hole in the corner

 

i have seen that ... bit pricey , at that price i can buy both 2007 doors complete and hinge them to my cab
