Civic OEM Strut Bar Help?

OK, so i own a 00' civic ex and purchased an OEM SI front tower bar but none of the bolts were included. Now my civic does not have the holes predrilled but there are indentations for where to place the bolts. Only thing is i'm not sure what bolts, washers, and nuts to use. If anyone can give me an idea of the proper supplies I need for this install? Or if anyone has pics of what I should use?
