getting rid of rear window wiper.....need a part

Looking to find the round plug that goes in place of where the rear wiper goes through the rear gate. I believe this to be on lower end XJ's that don't have the rear wiper as part of it's trim package. I stumbled upon one of these at the JY but let my friend have it for his XJ and would like one for mine.
