You could even use the old copper washer from the oil return banjo bolt; I've found you can turn them around and they usually will re-conform.
If I may play devil's advocate: You could also use the top end of the turbo oil drain and splice it into the AAZ block-side drain end. That is, of course, assuming you are doing this out of preference, or don't have an AAZ pan. Also, don't forget the AAZ block is taller than a 1.6, so using the stock line won't work unless you use an extension of some sort.
