Is grill also headlight mount?

[rickf]

I'm considering pulling off my grill to try to straighten is some. It hasn't bothered me much for the last 27 years, but all your pretty trucks makes me want to finally fix it.

I pulled the little headlight trim ring, and looked around. I found one bolt (per side) but there must be more, and it is looking like the headlight mount is part of it. I was not intending to disable the truck just to meddle with the grill.

Can the headlights stay put without the grill?
How is that grill mounted?
