The truth is, unless you do it for a living then you can't do it yourself. By the time you finish paying for the sunroof and paying someone to put it in, you could have bought a complete AC system and put it in yourself. If you look around, you can usually find somebody willing to charge it for about $30- but not in Hawaii. Last time I checked, Hose Wizard sold everthing you need for about $700, and I have never seen a sunroof job cost less than that that didn't have problems. It won't let as much light in the car, but it doesn't leak either and it's a heck of a lot colder.
