I'll be darned... Dave, Since your car and mine are only 4-5 days apart in Dearborn, I checked my brace areas, and sure enough, I have a punched tag sandwiched on the LH side. It definately deserves more investigation!! I can't see anything on the passenger side, but then again I still have my braces on the car. I am going to re-paint them soon..and when I do, I'll spread the panel a bit when the braces are off both sides, and I'm sure now that I'll find something!
