If you have older towers you can check our online fit guide for discontinued tower fits. They are listed near the bottom and are noted as "Historical".
If you do not see your tower listed it means it was not tested on your model of car. It doesn't mean that the tower will not work, just that we haven't tested it, so we are unable to provide fit information or cover the use under warranty.
If you need additional help please contact our support team here, or by phone at 888-925-4621 during business hours
