I just fitted 2012 Spanish leather Pathfinder front seats into my 2013 Spanish D40 Dual Cab.
They swapped in perfectly, bolts and space wise are identical. With one small exception being the single black cable for the passengers seat side airbag. It's a slightly different plug. However a quick cut and solder of the original wire off the cloth seat onto the leather seat should fix this.
The cloths seats were okay, but crudely basic, very crudely basic. The leather is much better, plus they are fully electronic! I don't see any compatible wiring harness under the carpet for the electronic adjustments, so I might need to buy the matching male plug and wire it in. Other than that, they are certainly better seats by a good mile and I'm very pleased. The pair cost me just $200 off a very friendly Navara driver.
