I just found a seller selling a k04 for 1996-2003 1.8t. Don't all k04 turbos fit the 1.8t engine anyway? they said the later version had a bigger flange, so might not fit, the seller is offering a very cheap price and warrantee on it, so quite tempted.
the description was:
Bearing: Journal Bearing
Downpipe flange type : Audi/VW 1.8 T3 Bolt Standard
Cooling type: Water and Oil cool
