Great looking job,
I've been contemplating doing a vinyl top, except that I already have the glass in, and I don't relish the thought of taking the glass back out then back in again.
I'm going to do the vinyl roof and headliner before putting the glass back in. I assumed that you could do both with the glass in but it would be a pia. The vinyl roof doesn't extend under the window gaskets does it? You could tuck it in?
