When I bought my TR3A brand new in 1958, there were no holes for the deflector. In fact, it came before deflectors were devised. I put one on during my restoration from 1987 to 1990. It came in 3 pieces and I secured the top center piece to the two side pieces with brass long stem rivets. Though it was black, I sprayed mine a couple of coats of aerosol black on both sides before final installation. Dick - if you car is red, spray the deflector pieces red. They should be body colour. By now I'd guess that there are another 5 coats of black paint on my deflector. This is for water protection so it doesn't rot or decay. I hold it into place with the two chromed top supports for the bumperettes. I drilled no extra holes. There was a crease in my side pieces that told me to fold the bottom flange forward and the upright flanges backwards to fit up the two sides of the radiatior. Don't drill any holes in the bottom deck behind the grille! Dick - I'll e-mail you some photos. Cheers Don - e-mail me at 58tr3a at videotron dot ca with your address.
