Dash removal question 65 barracuda

I don't know about early, but "it can be done" without removing windshield on the 67/ later. Now I don't know about AC, the car I did had no heater, radio, etc. You have to get up in there, and I used two die grinders with cutoff wheels-- my old axial air one, and a 90* cheapo I bought at HF cheap. You slice the sheet metal clip nuts and that allows you to remove it. Then reverse them, and in my case, I need just slightly longer screws to get them started, then when everything began to line up, "I think" I remember using the factory screws.
At least one other member here, I think Redfish, has done this as well
