Any help on how to remove the door windows on a 68 Post car? I'm thinking you have to remove the wing window, is that correct, or any other tips?

 

I don’t think I had to on my 65 post.

You remove the lower window stop.
Crank the window down as far as it can go.
Roll it forward until it falls off the rail/track.
Tilt it forward and swing the back of the window upward and pull it up and out.

 

Thanks for the tip.
