Head Rest Question
 

I have a1998 1.8L Quattro with a broken head rest. I bought one off ebay that came from a 1.8L A4 but it is a little bigger than what is in the car and it has a release button on the side which the head rest in my car doesn't have. Does the Quattro have a different trim level than other 1.8s? Or more importantly what models have the type of head test that is in my 1.8L Quattro?

Thanks,
Mark
