Question about grill and headlight mount

[JGross]

The PO had already removed the grill and headlights before I got the truck so I haven’t seen one put together. I will be replacing the grill that came with the truck with a new chrome one, the grill that came with the truck has the headlight mounts riveted on it, but in the photos in the LMC catalog the grills do not have light mounts attached. Do I need to keep the old mounts to attach to the new grill? If anyone has a drawing of have the headlights and grill are installed I would be grateful.

Thanks
