Explorers from 2001 and older will be a direct swap, same bolt holes and everything. I pulled a set of power leathers from a 2-door 2001 Explorer and they bolted right up.
Try and get them from a 2-door because then they have the lever that bends the seat forward, the 4 doors might have it as well I'm not exactly sure. Sounds like its time for you to go on a treasure hunt at your junkyard!
Just saw that your name has MX in it, you ride? Motocross is my life, my current stallion is an 06 CRF250 modded out. Probably be getting a new one sometime next year if Honda can get the EFI working right and release it next year.
