66 C10 Driver side door window

[53chevyforever]

Help....I removed the window on my 66 and replaced the rollers on the window relay. My window is now sitting at the bottom of the door and I have new whiskers ready to install and the vent window is also out. Not sure what I need to do next.
Do I have to remove the door latch? Do I replace the whiskers last or now?
It seems like the window on the passenger side is too high to change whiskers with the window in place. Step by step would help at this point
