Yeah I have actually! It's funny how that works sometimes. In fact, I have the same light bracket on my truck! It's also an 87 like yours. It confirms to me that my truck was shipped from the factory without a rear bumper and the step bumper I have on it is indeed an aftermarket that's been on it for a long time! I even disconnected my wiring from the license plate light on the step bumper and plugged it into the factory pigtail on the bracket, and what do you know? The original light lit up! I was amazed! Lol!
