Are the LED boot lights still available second hand over there 
The wide boot lights i mean like on this one 
You need the bootlid as well... as Elvin pointed out, the panel is bolted to the bootlid, so the metalwork is different...
As for the shape of the facelift outer lights, the non North America light units are a fuller shape, but the shape of the light location on the quarter panel is identical as the bodyshells are identical across the globe

To fit the facelift Catera lights, you need the bootlid, both outer clusters and all the rear light wiring. Legally they should be fine, as they use amber lights for the indicators... unusual for American cars. The led third brake light is about the same length as the one on my EClass, so no issues there either

Chevrolet Omega

For clarity, South America does things differently... the South American Omega A is the same as the European one, ie the Mk 2 Carlton/Opel Omega A. The rest, as wiki'dangle berries' says in plain english, are rebadged Holden Commodores, and have sfa to do with the Opel/Vauxhall Omega B that we know and love. Our Omega B was also sold in Japan, New Zealand, and the Middle east as the Chevrolet Omega just to confuse the simple folk
