I didn't install it yet, but how do the two deck parts mount to the stands? I'm just wondering cause on the boz it says "only use for racing or show applications, not for everyday driving" or something like that. But I don't think people pay attention to it, I'm driving with it in everyday. But I don't see how it mounts together? It looks like it just sits there? Or are there holes for it or do you have to drill some? Does anyone get what I'm trying to say?
