I'm in the Chicago suburbs... I prefer local sale as these are HEAVY!
Rocky Road Outfitters Super Sliders. These fit R51 pathfinder models from 2005 - 2012. Bought new from Rocky Road Outfitters and never installed. All original hardware, templates, and instructions are included. They are still zip tied to the super sliders. I never installed these and the pathfinder has been sold long ago.
See Rocky Road product webpage for details. These sell for $629 new, plus about $100 for shipping.
Pictures were too large to attach. I can send pictures to anyone interested.
