Just a hint for you, what I've done is make use of Fastlane's online catalog. I own a small fleet of Audi Coupes, an '82, an '83 and an'84 parts car. Most parts will interchange for these years, but they made some changes mid-83. So I pull up Fastlane, look up the part number for what I'm fixing, then pull up the part number for the part I want to yank off my '84 parts car. If they are the same part number, bingo! I'm set.
