Since the wife and kids are visiting the in-laws this week, I spent all of the 4th of July installing the windows and associated hardware. It took 4 hours to do the passenger side including an hour and a half wasted after I learned that I had the window sash channel that bolts to the window, upside down. I couldn't figure out why the heck the window would only go up halfway before the rollers hit the end of the sash channel track. After repeated attempts at loosening, readjusting, resetting, manipulating, manhandling, I just couldn't get it up (the window, that is).
After perusing the assembly manual (which was no help) I grabbed the flashlight and peeked into the window channel of my Grandma's '75 Firebird to see that I had the sash channel in wrong. DUH!
Once I got the channel in the correct position, it took another hour of adjusting to get the window situated correctly. It now closes quite nicely with the NOS GM weatherstripping.
The driver's side only took an hour and a half with adjustment.
And here's the final result after another 8 hour day.
