I didn't know these even existed!

Wait....powerstroke? I am *pretty* sure you couldn't get one in a FSB. Though...a four door Bronco aka "Bronco Centurion" was coachbuilt by Centurion who also made those fancy-shmancy F250 and F350 dually rigs you see decked out with captain's chairs and such for long over-the-road hauls. So they may have swapped in whatever they pleased.

I LOVE those things. To me it's the forebear to the Excursion. Too bad they didn't build a 2-door Excursion, to be like a modern next-gen Bronco!
