Find your local pick a part yards and make a few trips in there occasionally...Bronco 2's and Rangers had the same overhead push button system I believe, but finding them is getting harder and harder as more and more of these vehicles go to the crusher.
Maybe find a newer SUV that's been wrecked that has one of those rotary dial systems for the terrain management stuff, grab one of those and install it in the overhead console and make people think you got that fancy terrain management, crawl control, and trailer backup assist crap in your 30+ year old rig LOL.
