Stock 72 rear bumper?

[muddpile]

Before I start, I will say that I should probably have pictures for this, but unfortunately I haven't bought a digital camera yet. Anyways, what I'm wondering is what did a 72 custom deluxe come with for a stock rear bumper. Mine has a checkerplate top that folds up at the back and is rounded where the trailer ball goes. The provisions for the license plate are on top of it on the drivers side just below the tailgate. I assume its not original, but I can't say for sure. It doesn't have any sort of light on it.

What I would like to do is replace it with a nice chrome one. Preferably a stock chrome one, but I'm not sure what will fit and what is stock, whether any have a light (is that a law) etc etc. Pics would be helpful. Thanks.
