Replacing Driver Rear Window?

Hi all,

Got a 90 Delta 88 that I am replacing the driver side rear window in that got
broken. I have the replacment and am ready to install it but I can't get the darn thing in. I've removed the doorpanel, and the chrome strip with the "window brush". I can'tremove the outer "window brush" because the door
has one of those small windows that does not move and there is a screw behind it. Looks like I may have to remove the small window and maybe the
window track. I've tried several ways to position it but can't get it in. Could some one please give me some tips on this install.
It's kinda like a puzzle, it seems it can be done only a certain way.
Thank you!

I got it.
There are 4 Star screws holding the bar between the small window and the window I'm replacing. The bar & rubber window track needs to be taken out so the window will go in. Then replace the bar and rubber track then put window in place and bolt to window motor track.
