66 cuda rear window

I agree. The front window just pops out from the corner. Pull the lock strip and the window will push out and peel away. It can be done without issue. Rear is not that much harder. Pull lock strip and get on your back and use your knees to push window out at the top edge. Have a helper manage from the outside. Putting it back in is easier, just lay it on the gasket in the track and then start with a spudger (stiff panel nylon wedge tool) and start prying the gasket lip over the glass. It will suck the window in and then you just push the lock strip back in. You won't break the rear glass. Go slow on front and you won't break that one either. It's totally doable.
