the whole Headlight assemby will not fit flush in the car

As you already know, it can be VERY difficult to correctly reinstall the headlight assembly into a 2003 Volkswagon Beetle! All I can suggest is to make sure the slider inside the housing has some lube on it and be very careful to get each of the guides into their slots. You will need to work very carefully in order to get the retainers properly engaged to pull the headlight properly back into place. Does any one else out there have anything to add or any tricks to get the head light assembly installed correctly?
