Window mechanisms on Sedan Doors: Which first?

Hey, guys, I'm about to put the window mechanisms and windows back in my 64 2 door post car. They were a huge pain to get out of the car, and the FSM shows instructions for removing both the vent window and the door window, but not both at the same time. Looks like either can be removed independent of the other. Seems to me like the door glass could theoretically go in first and I could just slip the vent around it, but I figured I'd ask the forum first instead of wishing I'd ask while I clean up broken glass. What has your experience been?

Thanks!
