I turned down a 69 valiant grille for $100 this morning because it had a dent. I'm sure I can get one for $200 or under in excellent condition- no big rush. I know my sharkstooth is worth at least $600 so I'm keeping it.
I picked up a standard duster grille in excellent shape yesterday for $90 and I'm painting that one flat black and installing it until the right valiant grill comes along.
