Way old thread I realize, but I bought my Frankenstein 67 with a 69 grille already installed. I can't say it's an amazing job and don't know what else they changed, but it's on there. I know the rear quarters were replaced with new sheet metal, but any marker lights anywhere on the car have all been welded up, so don't actually know what they may have started life as. Entirely possible they swapped 69 front fenders on at the same time for my car.
