I recently bought a carbon fiber type r wing from jdmshit. I was wondering if anyone else has bought the same product from them as well??????

Problem I'm having is the wing i purchased from jdmshit didn't have the bolts on it. So I assumed I could take them off of the factory spoiler but it turns out I couldn't. Just wanted to know if anyone had the same problem and can somehow tell or show me how yall installed the wing as well, thanks.
