Im looking around for a //S logo and a OOOO logo for the trunk lid of my 85 4kq in place of the QUATTRO and 4000s , I was wondering if anyone knows which year of car I can use them from and if its not asking too much the dealer part # for it. I was thinking of the //S from an S4 and the OOOO from an audi 200. unsure of which year is best though. TIA! David
