From memory when I had to replace a ballast, removing the headlights is oddly complicated. There are some bolts on the back that will require removing the fender liner and IIRC there is a very awkwardly placed screw near the radiator that has very limited space to reach. Before starting, check that you have enough oddball tools to reach in and remove all the fasteners.
