I got the Morimoto H1 kit (with balists, lights, projectors, and harness) the problem with some of those other kits are that they don't have the right harness you would need (since the 9007 and 9004 use the same shape socket part). There is plenty of room infront of the lense to the factory glass( which is really good).
I also think there is a dl in the junk yard near me... here's a pic are you talking about those rectangular ones?
