When I did my explorer seat swap, I was having trouble with the seat belts. The belts off the old seats had the pretensioner, which the explorer I got the seats from did not. (Pic of the seats

I couldn't figure out how to get the cable out of the holster housing, so I looked for a new seatbelt holster.
I then realized that the rear seat belts for the jump seats are the same size as the driver and passenger side. I took the door panel off and took the holster out (it's a large torx head) The explorer seats had a metal tab from the seat belt in the explorer, and I just used a bolt and a nut to secure the holster. Once I get a center console in it'll be awesome.
