I want to use a pc cord with my Nikon Sb-600. Is this the correct part I need? http://www.bhphotovideo.com/c/product/133218-REG/Medalight_PGHSPC_Hot_Shoe_to_PC.html The reason I am unsure is because that seem to be made for the camera's hot shoe that feeds to a pc cord, and the top hot shoe does nothing but hold something. So, how do I connect a pc cord into my Sb-600, which has no connection for one, but only a hot shoe on the bottom? Thanks.
