Yes, I was able to get an original grille, with old GM sticker still on it, and inner fenders, and a tailgate, old dealerships with large unorganized parts barns can yield some treaure.
It also helps when the owner of the dealer also collects old cars/trucks, so they understand.
The only drawback is when you call and get some person who only can look at a computer screen. But, that happens at all parts stores sometimes.
