Looks like Ames and Performance Years have them with the body brace attached. Performance about $75.00 each. Ames about $70 each, NPD lists them for Chevelle, say US made, and look about the same size and have thee body brace, for $63.00 each. I have bought from Ames and Preforance but not NPD. Any thought if the same panel, and are Chevelle the same as BPO in that section of the trunk floor. Thanks Bill
