2003 z71 roof rack end cap-where to buy?

[Michigan]

I just purchased a 2003 z71 Tahoe and the end piece closest to the tailgate on the passenger side is missing. I've done some research and looks like this is a common piece that gets stolen. Lol. Not sure why but does anyone have any idea where I can get one of these from?
