A while back I posted asking for info on a replacement sunroof seal on my Gen 3. I know there is at least one other person here that will benefit from this info (Black95Cam). If there is anyone else out there that has the "built-in" sunroof with the ASC button on the controls and is in need of a replacement seal or other part, this is for you. I initially thought that the model for my sunroof was "Gaurdian" because this was printed on the glass. This is not correct. Turns out that the company is "ASC", or American Sunroof Co. Apparently the founder of this Co. offed himself and ASC merged with Inalfa and is now called ASI or American Sunroof Inalfa. This company has installers all over the place. Below is a link to their site where you can search for an installer near you. Hope this info helps.
