First off, Welcome!!!

Pictures help out a lot. But I can answer a few. The bumper is an 81-82, if I remember right. I have that bumper on my 86. You can get new at LMC. Here's a pic of mine.
This also what the grille should look like. Mine had a Billet grille when I bought it, but I went back to the stock grille. This style of grille ran from 85-87 on the trucks. They ran later on the crew cabs, suburbans and blazers.
And yes, it should have a hood ornament, but most people don't when the Swap hoods. Again, mine had a Cowl Induction hood when I bought it, but I going back with the stock hood, and putting the ornament on it.
