I have a problem in which one headlight is too far forward and the headlight is catching on the bumper and 1 not coming up all the way and 2 only coming up at all if my car is on.

Is there a way to adjust my headlight back further?

 

this would be a question to ask on ls1tech or similar site, this site is more specific to 3rd gens, 1982-1992. I could tell you how to adjust the headlights on my 86 bird, but not a 4th gen.

I would assume however, that there are bolts holding the headlight assemblies to the radiator support that can be loosened and allow you to move the light a little in any direction and possible fix this issue. Unless the issue is that the car was hit, then you may never be able to fix it with major repairs first.
