Urgent: Replace rear driver's side window

It's for a 90 Century.

So the last window was broken. Bought a used one at a junk yard for $45, drilled out the rivets on the plastic bushings, mounted the bracket on with nuts/bolts with industrial LocTite, everything is out and in the garage, I just can't get the window in the door. Any help here? I can't even find a video on YouTube. I need to get this done by 5pm, maybe even a little later, just need to get it out of the garage. I work at 6am tomorrow and don't want to drive to work without a window.

Have the regulator all the way down. Install window from outside door frame, ft corner first.

Didn't work. Tried it several ways. The regulator doesn't move, but it isn't in the way, either. It's like one of those mind trick puzzles where you think there's no way to do it, and you finally figure it out. That, or I have to use a grinder to cut away at the window frame. I'll ask my body guy that's working on my Celica. Hate to ask him again, but I gotta get the window in.
