The top image is a K2-3 bike. The lower one is K4 onwards. (Actually it's a 650, but the same design, 1000cc had chrome rings around the clocks)
The seller has got it wrong.
I'm not sure if the support frame differed, but the textured black surround, clocks and side panels, screens all varied.
Someone did botch a later fairing onto his K2 a while back, but it took a lot of work and still didn't look like a factory finish.
I think he did it to get the later model screen options and more modern dash.
Stick the new one back on ebay, it's not likely you'll get sence out of the seller to get your money back.
