Hello everyone I need help on a question My Audi has a Delta radio in it as of right now but sadly my cassette player doesn't work...So i went on eBay and bought another Audi radio but it is the concert one, Now it came out of a newer A6 )(1998) and it was a great deal ($15.67 with code) But before i take out my delta radio and put in the concert one do you think it will fit ok ??Has anyone done this before ?

Thank you for your help,Mitch
