I went to the metal fab shop and had my profile made up, they did have to make the trailing edge that welded onto the body a bit longer to get the correct bend, but that was easily trimmed to fit. for the curved secttions they used a shrinker for the perfect compound curve supplied by me using ahem.... duct tape and cardboard:D as a pattern. cost about $80 for the 3 pieces. mine was for a 66 not a 69 but should be similar.
