Yes, I just did mine on my '27 coupe. Glass goes in from the top. Be sure to get the slant right, it slopes to the front. Then, I slid the channels down the sides. I found the outboard channel needed to go in first, then front.
I used silicone spray on the back of each channel and used the glass to work each one down in place. It took a while, but we made it without breaking the glass....the car had no windows when I bought it, so I spent quite a bit of time in "contemplation"! It also had no regulators. Had to do some creative fabrication on those, too.
Good luck!! You will be very happy when that new glass rolls up and down!!!
Dick.
