change 2003 halogen headlights?

[dbreda]

OK, probably a stupid question, but I need to change my burnt out headlights in my 2003 S-10. I bought the bulbs, and unscrewed the top mounting screws above the headlight assembly. The assembly now tilts forward, but does not come out so that I can access the bulbs in the back. What am I missing? It feels like there is something holding it in near the bottom of the assembly.
