I don't know how its been ignored/not found that one thread that had a how to on making lexan lenses to put on the stock housing. For the life of me I can not find it anymore, and I used to have it saved on my desktop... bummer
Anyways...
It consisted of taking it apart, pour cement, or plaster of paris into the glass and let it mold and harden.
After that take the mold and shave the flutes off of it to make it a smooth surface.
Then you heat the lexan up and quickly press it over the mold and let it cool.
After that just take a dremel and cut off what you dont need...
There you go, you have clear plastic lenses for your square headlights, and while you have the headlight apart, might as well put in projectors.
And always make sure to very liberally use the silicon to close the housing, you dont want moisture in there.
