Review on URO Parts 210 827 0031KIT Roof Antenna Upgrade (Including Antenna Tip & Gasket) by Tommy Woods

Bottom seal fits perfectly. The antenna's rubber tip is a little tight from the factory hole, but I used a little patience and some soap to lubricate the process. (Make sure everything is wiped dry before attaching the lid.) I didn't drill a bigger hole as some reviewers have mentioned. Just be careful and take your time with the installation. I installed the antenna tip from the bottom of the cover up. The screw that holds the cover to the roof has a small O-ring (not included). So be careful not to lose it when removing the metric hex screw. Easy to fix, great product and looks great when finished.
