Someone else can tell you when the size changed, but my 1680 had a 10 inch clean grain with bubble up. It was a late '91. I'm wondering if it wasn't just the 1480s that had the 8 inch and horizontal auger. If this is so, I'm thinking there wouldn't be that much market for what you're talking about. It'd likely be easier to retro the CIH 10" as well.
