Everyone has been giving AMD these great reviews and putting them up on a pedestal. Truth is that they are the same as all the others. You also have to keep in mind that every car is a little different. These cars twist and bend. Nothing I have gotten from AMD for my 69 has been easy to install. People use to talk about the "X" in the part number. I don't think that even factors in anymore. Just know what you are buying is not original , and expect to have to work to make it fit to your expectations. These cars had inconsistent gaps to begin with , and many want better than original. That will make more work for you too.
