The template I made was from cardboard. Once I had the shape I wanted, I transfered the shape to plexi-glass. Once the patern was traced on the plexi, I cut out the shape, and then sanded the edges flat and once smooth I painted it black and then put a coat of clear on them for protection.
Drilled the holes through the plexi splitters and bottom of the lower lip and bolted it all up with stainless hardware to avoid rusting.
There was no outside company that made these. All done by myself in my garage and in one day.
Hope that helps you guys out that want to try and make them on your own.
