i broke one of my 'driving' lenses on some 2000s and since it was just a clear lens(not a fog dispersion pattern), and i had it sitting around i broke the rest of the glass out/ off the frame and cut a piece of lexan to fit. glued it together, and its been fine since. just doesnt' say 'hella' in the middle of it and if you knock on it it sounds like plastic not glass.. oh well.
(i hope its not bad to post tech in the 'parts wanted section')
peace
