I've very recently bought a 2005 A4 B6 cabriolet with a good body and many mechanical problems. One front wing has some bubbles at wheel arch and I investigated a replacement part. Very quickly found that as I suspected the cabriolet wing is different at the headlight and also at the A pillar. Official Audi parts lists the standard A4 B6 wings as 8E0821105/6 and the cabriolet B6 as 8H0821105/6. Only a letter different but nobody has manufactured a cabriolet pattern part (c£30 up) so Audi only at c£230 from Latvia and I know not what from Audi UK. Experts will correct me if I am wrong. I'd be careful of used parts due to age unless ordered from somewhere sunny or can be inspected. Welcome to the world of niche products.
