they are nice.
I am biased to the argent finished 70 standard grille. So often people put a grille emblem on 71 and 72 because they all have the hole for it ......but Grille emblems are for 70 only silly.
I have a wrecked 70 duster 340 that I was in the process of using the parts to make a 72 shell look like a 70 ....not sure about that project now.
The 70 340 car is CRUNCHED ...BIG TIME!!!!!
the 72 shell is it's only chance of re-incarnation.
