Need advice or illustrations on removing and replacing the items listed. Diagrams showing bolts and retainers would be especially appreciated
Here's a diagram of the headlamp assembly. It requires snap-ring pliers to spread the 3 headlamp mounting clips. Then you can pull the headlamp out.
We don't have the body R&R procedures and diagrams for this one. That's typically only part of the factory service manual. As far as the grill and fender are concerned, it's usually just a matter of examining where all the fasteners are and removing accordingly.
