Here is what I found out today:
Junk yards are full of Explorers. Most of them have trashed drivers seats.
All the Explorers from 91-2007 have basically the same seat sizes (outer diameters). The seat faces are wider but the overall width are nearly the same. I measured out 2000, 2002, 2004, 2007, all within an inch of my 94. All the electric motion controls are on the seats as well. Mounts are different, but not so much that they can't be modified to fit a 94. Including the rear seats. This would not be a job for the inexperienced fabricator, but anyone who can figure out an SAS should be able to make them work.
Just for info, the Flex, Escape and Expedition seats are all very close, but the mounting is so different it might not be worth the trouble.
One of the main issues would be disabling the air bag on 99 and up models before attempting to do any wiring.
Went to the first yard and they had the seats I saw in CL add yesterday. Perfect tan leather 2007. Problem is they sold the driver seat this morning. Guy offered me $175 for the rest. Need the complete set. I also found a set out of a 99, tan leather with a split in the driver seat that could easily be repaired for $150. I bet I could get them down to $100 cash.
The search continues.....
