Adjusting window frames, 68 American

yes those bolt can be loosened up to remove the window frame and for window removal and do slight adjustments

You were lucky you  could adjust yours. My SX4 had a factory defect right door window frame. I mean it was BAD. Funny thing - it was made that way in 1982 and my wife noticed it one winter several years ago while driving the car to work - "I feel cold air coming in". Door was closed, window was up, heat on....
We got to a stop and I reached over and yeah, I feel cold air coming in - then I looked up and could see between the window frame and door opening! I could slip paper through there, almost my little finger. 
The window frame was shaped wrong. No, it wasn't bent or damaged. All welds were fine, no sign or any cracks or breakage anywhere. It was simply a defect. Obviously the prior owner(s) lived with it all those years. (seeing how they treated the car, no shock)
Even the body shop that later sprayed the car for me admitted - factory defect. I had a parts car I cut the window frame out of, too the door and other frame to the body shop and they cut out the bad one and welded in the better one. PERFECT FIT now, seals all the way around, even contact of the door seal. 
They are welded in place on the later cars. 

those door never sealed properly when they were 10years old I always remember wind noise in my dads old ramblers we had anything from 66 to 69 in early 70

Funny, I remember the opposite. My grandparents always had Rambler Americans, for my parents, once they got beyond the 1940s Plymouth coups with caulking to seal the rear window and windshield, they moved to Ramblers - Classics. Between my parents and I, we had 3. We took the wagon on vacations to MO, SD and so on - a lot of highway, never a noisy car unless you count three brothers in the back seat fighting all the time......
My grandparents' Americans - rode with grandpa quite a bit and don't recall noise. 
I even worked in a shop that had been part of a dealership - most of our customers were Rambler owners - and we did test drives on 141 west of town (open flat highway). 

Whatever, I just never remembered the Ramblers as being noisy - now the hardtops were another issue but those weren't bad once the glass was adjusted properly and the seals were good (Javelin, etc.)

Mom and Dad always considered their Rambler wagon to be sort of a luxery car - and for them it was!!
