I could well be wrong but I didnt think they did........only because I was stewing over the idea of changing bodywork, as in applying SV6 bumpers to the calais, front and rear and I thought the panel seams differed.....I wanted to leep the calais rear lights on the SV6 rear but the bodywork takes the smaller light....which is in essence the same size as the Berlina and Omega.........if I'm correct I thnk you may find the Calais taillight is about 40mm deeper
am happy to stand corrected
