I got a big hole to fill in the roof of my 32 Plymouth sedan and looking for ideas. Other than cutting a roof out of something else, what other options? I'm going to have a friend that does wood work to make the bows or cross pieces. It has a recess of close to an inch and then it has the groove around it where I guess you nailed the original on. That groove all the way around and the fact that it has a contour both ways presents a problem. I was thinking of a piece of plywood, padding and marine vinyl but I don't think it would contour right with the roof and end up with flat spots.
