I wish to purchase a new bumper for my '73. I've purchased a TruFlex bumper and it won't fit due to it's sizing. I asked around and I've got the impression that I must remove the front impact bar in order to install a bumper (TruFlex or otherwise). Is this true? I'm no expert, but I am not thrilled with the idea of removing a vital part of the bumper just to fit an ill-designed TruFlex or fiberglass bumper. Am I making a mountain out of a mole hill here or is there a bumper I can purchase that is designed correctly and fits over the standard impact bar?
