Fabbing Tail Light Lens

[Bigblue73]

Is there any way to do this? I've seen some done before but I have no idea how it was done. Specifically, I'd like to make a one-piece lens for my 66 Nova. Here is an example - the only one I know of and I was told it is a one-off custom (NovaStar2). Or an alternative would be to replace the backup lens with a red one.

First off - I dig the exhaust on that car.

Have you ever thought of using a just flat sheet stock and using a diffusing film on the inside to disperse the light. The film is like a frosted mylar that is used on gas pump displays and other large displays to spread the light evenly and minimize the "Hot Spots" with bulbs, LED's.... One note, I have no clue if this is legal for the street or not.
