Window and Drip Rail Molding Assembly Sequence Question

[Gary AAR]

Getting ready to install the door and quarter windows in my 70 Cuda.  I have not yet installed the drip rail molding and weather strip channel.  Question..... should I install the windows before or after the drip rail molding and weather strip channel?  Or is either assembly sequence acceptable.  Didn't know if installing the windows prior to the drip rail molding being installed would give me more maneuvering room when installing the windows. 
Thanks for the help.

You can go ahead and do the glass first, but I would leave it loose, because you won't be able to do final adjustment until the roof rail weather-strip is in place
