Thanks. The most obvious way to identify them is by the 3/4"x1/8" crimps around the front & sides. You can just make them out in the pic. Naturally a magnet would help, especially on the trunk, which doesn't have any "crimps". I'm pretty sure some came with all steel trunks because I went to buy a set once and there was a "problem". The colors matched perfectly and the seller swore that they were off of the same car.
