I have not actually driven with it on yet. I was going to wait until I get the 2.0 version of clear poly setup. I hope to go and see what my friend has at her shop this week. I have found some 1/2 galv pipe clips that I may be able to bend into a clip and then have something to hold the poly with or some old aluminium rod hangers that are flat. I am thinking I could use these on the sides and still try and have some tabs put in to the front of the form at the top of the glass to silicon in place on the glass. I know what you mean about the light housing.
