Hugger69, I ran into this problem a few years ago and found it wasn't the guards instead it was the bumper. The guards were made to fit the original bumper, not the repro. I have a 69 here that the customer wants me to add the tall front guards to, but I know I am going to have a time fitting them to the bumper as his car has an older repro bumper on it now. I have heard that these guards do fit the top of the line bumper from Goodmark, but I have not confirmed this with a test fit of my own. They did some serious retooling about 5 years ago on all of their bumpers to be more exact on exterior shape as compared to originals, and of the ones for the 67-68 models they are pretty much dead-on. You are doing about the only thing feasible to make them fit, which stinks because now you have to either rechrome them or paint the edges that you grind............................RatPack........................
