Not sure about the 69, but the 67 type I have seen are soft, some moldings aftermarket are pretty good for 67's, like the eye brow moldings are descent, it is still rigid and color is good where like the hockey stick moldings feels like putty if that makes sense? You can bend them to fit, but the bent is noticeable..... I am not sure if it's the manufacturers or they haven't got the angles down yet? Have not seen the lower trunk or hood moldings for the 67's cause I don't need them, so for the hockey sticks I sent the moldings out and had them re-anodized,(much better).
If NOS not available, after spending that kind of money on a restoration, I would have old ones straightened / re-anodized, I think in the long run, you won't like the a/m wheel openings, May also depend what you plan on doing with the car maybe? driving it or trailering it? Only you can decide if your happy with them once they are on, and if you go back to originals do the screw holes line up?
my 2 cents
