I only got the passenger side of the lower partial grille block done so far, but I have the sheet metal cut out for the other side and the middle-and-upper grille block. Hopefully all the main one will require now is some bending and finagling to get it into place.
Here's some pics of the lower part I did get done.
The other side will look the same. I'm going to work on putting some ducting in on the sides there so there's less of a lip for the air to travel over. I don't think I'll be able to seal the whole passage from there to the radiator, but I'll do what I can.
