I've got a set of Bushwacker cut-out pocket style flares for 84-01 Cherokee. The set is missing the passenger side front flare. The other three corners are used but in good shape. They have been modded to fit a 97+ XJ. I also have a brand new hardware/installation kit that will come along with it, so disregard the crappy looking trim in the pics.
I spoke with someone from Bushwacker on the phone and they gave me the part # for the passenger flare and said you can call and order just the one from Quadratec or any other vendor who sells their products. It's about $130 for the replacement one.
