VW part from the Volkswagen 'tradition' type site is your item.
You'll find it on 7zap for golfs of the era. Better material, cheaper. Likely next day delivery. If I were at home, I'd send you a couple, as I bought a small quantity against future need. But I'm out in Asia, so no joy.
I'll dig up the part number shortly (191721559 I think is the dude)
Items 6 & 7 are actually the same thing. Change both, have a couple spare fro if it happens again in 20 years....
