I bought my header panel from cjponyparts.com. I was not happy with their shipping or product. It took a month for me to get my parts and when they came in the header panel seems to be a little too thick. I had to shave my headlight adjuster tabs to get them to clear the back of the panel so I could insert the metal retainer clips.
I would suggest American Muscle because I have never had a problem with their shipping. I don't know what their header panel will be like but it couldn't be any worse than the one from cjponyparts.
Which ever you decide to do, if you need any tips on it I would be happy to share my experiences.
