My hardtop was damaged by someone pushing my 280SL into it with great force. The hardtop was standing against the wall of my garage in front of my car. The rear glass and one side glass was broken, the hardtop twisted, the headliner punctured and the top dented. A very good Metal Man did rebuild the metal structure, fitted it on the car and removed the dent. I have obtained new glass and rubber sealing strip. We were wondering what the sequence of operations should be: Painting, then install the glass, then install new headliner. Or: install new headliner, paint and then install the glass. Where can I get the original headliner material? Help please!
