| Re: Rooftop Carrier You can purchase authorized GM crossbars from the GM accessories web site at gm.com. Caddy wont sell them to you if you go to the dealer. At least mine wouldn't, so I went on line, purchased them, and then picked them up at a local GM dealer in about a week. They work fine. I now use them to cart around my hunting canoe when I am driving out to fish or camp/hunt. Work perfectly. |
