I bought both off of ebay. You just tell them you're paint code and they paint it and ship it out. It was $160 shipped. The bumper was $153 shipped.
The valance Iis a genuine gm part but the bumper I'm sure is Chinese junk so hopefully it doesn't rust up on me, which if it does I will just paint it. But fitment, fit and finish on both the bumper and valance were perfect. Fit like a glove and every hole of importance lined up perfectly.
