Headliner installation "can i do it myself?"

I did the one in my Dart. Turned out ok. Sail panel area is the hard part to get smooth. Heat is the trick. They don't like to stretch unless hey are hot. I did mine in the summer and let it lay in the sun for a while before I put it in. Now that I have done one I think I could do an even better job on the next one.

I used the end of a flat paint string stick to push the liner over the barbs in the front and back window area.
