What I think I've learned is that Bronco and Ext Cab seats are unique to themselves and can be swapped amongst themselves.
All regular cab and crew cab seats are interchangeable as long as you move the seat pan with them, even front to back.
If I remember correctly, the Bronco and Ext cab seats can be put into a regular cab and a crew cab if the front/back adjuster tracks or the flop-forward track is removed from its seat base and bolted to the proper standard or crew cab seat base.
I believe I can move my front 40/20/40 seat to the rear of my crew cab when I find a either another 40/20/40 seat for the front or a great condition set of seats from a Bronco or Ext cab and will remove them from their seat bases and put them onto an extra 40/20/40 base I have purchased just for this upgrade.
I hope this helps.....
