Hi guys and gals, I’ve looked all over and yet have I seen a company that makes a spoiler like this for the trans am. I seen this picture on the internet and wanted to know has anyone did anything like this. I’ve contacted a few shops that do fabrication work but no luck. Does anyone know any businesses that already has something like this out there already? I’m guessing that this was custom made. Thanks in advance
