I pulled this tailgate panel off an 85, what other years is this correct for?

I'm throwing it on craigslist, unless someone on here wants to buy it. It has 2 small dents, one on each end. They can be fixed easily.

 

I have the same panel on my '86. I know they were on the 80-86 models. Can't say for certain they were on the 87-91

 

I know that they will fit any 80-96 bronco, and the 87-91 were different than this one. But there was a different styled one in the early 80s, I just wanna figure out what year they made the change so I can advertise it correctly.

 

The panels changes regularly with the styling updates in 1980, 1987, and 1992. Rule of thumb, when the body styling changed, so did the panel.
