Review on Towing Mirrors for 1999-2007 Ford Super Duty F250 F350 F450 Side Mirror Pair - Power Heated with Signal Light (Upgrade to 2008 Superduty Retrofit) - Fits 1999-2007 Models by Jason Bellman

Only giving 4 stars because the fit isn't very tight and the gasket material included doesn't look like it will let water through. These mirrors required no special tools or modifications to install on my 04 F-250, they are plug and play. It was a little tricky to remove the inner door panels but I figured it out. The blind spot mirrors are much better than the factory mirrors, and so are the main mirrors. You don't tremble much. These are good value for money, just check them carefully before you install them and don't believe people who say you have to cut them before you can install them.
