I've got them front and back. If you need to take a look at them or take photos you are welcome to it.

Each of the bar mounts are black with 4 lug holes and Spoon stamped into them. (F/R)
The bars themselves are polished Al and have no distinguishable markings. Front bar is slightly raised in the middle and the rear bar is straight across.

When you install them, take your time to do it right otherwise the rear will look like crap.

Not sure if that helps or not. Let me know
