This was on my truck when I bought it. Previous owner told me it was OEM and installed at Nissan. I've been searching around for a fair price for this item and it seems that around $300 is reasonable (or best offer). It would be available for pick up only at this point since I think shipping would be too expensive. I'm located in Somers, NY (about an hour north of NYC).
EDIT: Guard is made by WESTIN and is polished SS not chrome.
