I think we need to make a sticky for what year Explorer seats will fit the ranger! So you have an 04 reg cab, most likely explorer seats are not going to work for your truck. Regular cab rangers have longer Seat rails so unless you can find manual seats from an explorer and swap the seat rails you will be set. Or just make custom seat rails for the explorer seats. I have 02+ Sport Trac seats in my 04 Extended cab and they bolt right in. Also 02+ Sport or Sport trac seats maybe to wide so if you can find seats from a 98-01 explorer they could work with seat rail swapping.
What will fit:
98-01 Explorer 4door or 2door
02+ Sport Tracks
02+ Ford Explorer Sport (2door)
02+ Explorer 4 doors do not work for any ranger. The seat rails are very different.
