Facelift bought… and now?

Ahoi you guys… Did I just get on Ebay en Facelift… Unfortunately I don’t have a plan on how to install the part… So I’m dependent on others. But is net wrong if you know something about the conversion yourself.. What does it have to be done? Does the part fit the original points? An angle plate should be there. Does it have to be drilled? Is there an easy-to-use instruction in the www? Can one of you give me an instruction? Or is everything done by yourself, if you first have to work with In the product description there was garnix from ner AGB or soo…. So I don’t need an OR either? Does anyone have any idea if there are LED rear lights for A3 8L Bj. 98? At Ebay I found nothing!
