Hi Rico, just checked out your grilles on Shapeways. Fantastic work! I am in the process of gathering parts to build a friends late fathers 77 Scottsdale. Funny, I was just about to start cutting the center out of the grill due to the truck having a hand made tube grill insert. Any chance you would make a tube grill insert for these Chevy/ GMC grills in the future? That would be awesome! IMHO!
