      Building a rear diffuser?

      Have any of you guys ever built a rear diffuser for a project? I have a '68 Charger that I am working(don't worry Im used to having no one make parts for it) that may benefit from one. I do not want to get into a debate of wether I need one or not. This is just about how to make one.

      Obvioiusly Id smooth out the under body of the car and put a large flat plate under the car with the leading edge aimed at the rear axle and tilted up as high as possible. Then I would toss a few vertical fins on it and be done. What I am curious about is how could I do it? I can mock it up out of card board easily enough but how could I go from that to a piece I can fix onto the car? I cannot weld aluminum and I would prefer to do this myself. Im thinking maybe if I could get a big flat piece of fiberglass, I could make it from that but where could I get that? I could epoxy the pieces together. Any other ways I could do this that would be relatively easy to do?
