I've gotten the new Sunvisors in the mail from Nextgenparts.com but when looking and trying to install the sunvisors I noticed that there's no hole for the screw that supposed to go in? what do i do here? is there a hole for the sun visor in the prefabricated Sunvisors or do I have to drill one or what has anyone else run into the same problem??? Please help should I bring to dealer??? or a custom shop???
