Plymouth Duster 'Correct Exterior Treatment'

What about the front fender badges on a 1970 340 car? It appears the "Duster 340" emblems were stickers and it appears some had the V EIGHT and VALIANT badges but not all of them. My car was a /6 originally and has the holes in the fenders for the Valiant badges. I have a pair of V EIGHT badges I was going to add if it was correct.

I've also notice some have top fender mount turn signal indicators and some do not! Was this optional too?
