I had a leak in the seal for the windshield, went though the dealership, and they had a 3rd party come in to install it after they ordered the OEM. Of course this was all warrantee work, but if you have comprehensive coverage you should be able to get the insurance to cover it even with an OEM. But that said, start by calling the dealership, see if they have a windshield 3rd party installer, and then call him and ask for the OEM.
