I don't have an NOS rocker, but I do have a GM replacement that was brazed onto a pickup that had an accident back in the 70's or 80's. Its not perfect, but it is rustfree and I removed it by grinding thru all the brazing, so the rocker wasn't harmed in its removal. It is definitely not a repop. Has a dent toward the front and it needs to be cleaned up. Got more pics if you're interested.
