Cameo56,,Bill is correct about the grille being TOTALLY dissasembled when taking it to the plater. Grind off all the rivets so they dont have to. The plating $$$ will be high enuf,to where you wont want to pay them any extra dollars for what you can do yourself.
Chroming has gone sky high,,but dont skrimp,,use an established shop with a good reputation. You dont want to have to re-do it 3 or 4 years down the road.
I found that out the hard(and expensive) way on some of my parts.
