Yea I got that kit for like 40 bucks I think, Had to use there bulb sockets since the factory ones didnt fit into the lights. oh well, I saved the factory ends.
Ya, that sucks about LMC, you have to do minor modifications. I bought mine there and used a utility knife with a new blade and widened the "+" tabs to allow the Ford factory 1/4 twist plugs to work. Very easy to do, not much material has to be taken off. (I used the old cracked lens as a guide) Other than that, they fit 100% to the roof and have had no issues for water, but I did use the factory grey gaskets from the original lenses, they are thicker and compress better when I tightened the cab lights down.
