I did this very same thing and it was pretty easy. I found a grill with lights and hood latch already installed at a swap meet for $75. Never tried but the latch and brace may be the same. Also got the headlight buckets and bulbs from someone else at the swap meet for $10. Just drill out the spot welds on the GMC core support that holds the headlight buckets on. I used the mounting screws from the old GMC buckets. No wiring change is needed, just plug in the 3 prong connection and leave the other hang.
