It's good that someone helped you out. But the hot item, back in the day, was a KG brand. They had a set up that went both ways. Either a backrest that could fit a luggage rack, or a luggage rack that could fit a backrest Tall or short backrest, and large and small luggage rack. Universal fit, with unique install kits for most bikes. I have the large rack on my 350F. But it needs new chrome.
