Awesome... Thanks! This is what I was looking for. As you can see, they are somewhat similar but the Tempest pattern has 2 sets of 6 tight vertical ribs and 1 thicker one whereas the gto has 3 sets of 5 tight vertical ribs with the outermost two have an extra thicker rib...
Also, I can just make it out but it seems that the GTO has horizontal ribs on the door panel vs. vertical ones on the tempest... (Do you have a fuller pic of the door panels?)
I think this is something I can show these folks.
Thanks again!!
